    Hi, can you help me on BE1.6 on the revision please. Thank You

  2. Jodie says:

    Hi,
    I was just how you would do 6 divided by 2/3.

  3. Kayleigh Bell says:

    Hi mr macintyre I am stuck on revision paper 1 question 3 b I am not sure if x = 2.25 Or 2 1/4

  4. Kayleigh Bell says:

    5x-10_>8-3x

  5. Kayleigh Bell says:

    ok thanks

  6. Jenijo Macfarlane says:

    Hi I am stuck with the sum when you have to work out the percentage that’s equivalent to 7/50 ?

    • Multiply the top and bottom number by 2 Jenijo.

      Giving 14/100 = 14%

    • Jenijo Macfarlane says:

      Hi can you also please help me with
      3. calculate the area of a rectangular floor which is 7 1/2 metres long and 5 1/3 metres wide.
      4.Pippa has a weekly piano lesson which lasts 1 1/4 hours. If she sat her first examination after a total of 25 hours of piano lessons, how many lessons had she needed?
      I completely forgot how to do these…

      • Q3 is the area of a rectangle so length x breadth. Multiply the 2 fractions Jenijo.

        Q4 is divide the total number of hours by the length of time for one lesson. So divide the 2 fractions.

  7. Jenijo Macfarlane says:

    Thank you for getting back to me will work on that now.

  8. Kayleigh Bell says:

    hi Mr MacIntyre i was just wandering how you would divide a whole number with a fraction cause i am stuck on 6 times 3/4

  9. Jenijo says:

    how would you do Q.4 because I only know how to divide two fractions but the sum is 1 and 1/4 then 25 so I don’t know how you would do that ?

  10. Kirsty B. says:

    how do you change 121/2 % into a fraction? (revision booklet- fractions and percentages 3. d) )

  11. Jodie says:

    Hi,
    See for the questions; -5(5x+4)+6x
    I know it goes to -25x -20+6x
    Would you signs change if you move them to the other side

  12. Jenijo says:

    Hi, how would you find the median number of goals scored what would it be ?

  13. Jodie says:

    Hi,
    How would you do x/5=10

  14. Jenijo Macfarlane says:

    bc3.1 q 2. (c)

  15. Jenijo Macfarlane says:

    the middle number is one. Can you please help me with BE0.3 Q.1 (A) 6x 3/4 because I know how to divide two fractions but I don’t remember how you would do a whole number and a fraction ? Thanks.

  16. Jenijo Macfarlane says:

    Thank you Mr. Macintyre.

  17. Jenijo Macfarlane says:

    See on BE1.3 Q.3 (A) -10/5 would it be -2 ?

  18. Jenijo Macfarlane says:

    I am struggling with BE1.4 when you have to solve the equations… I cant find explanations in the textbook is there a page that explains how to do it ?

  19. Kirsty B. says:

    ok thank you

  20. Jenijo Macfarlane says:

    ok I will come at lunch then because I have wrote down everything I am not sure about. Thank you.

  21. Jenijo Macfarlane says:

    Two dice are thrown. What is the probability that:
    (a) The probability that the sum of the two dice is 7.
    sorry Mr. Macintyre how would you work this out ?

  22. Jenijo Macfarlane says:

    so would it be 6/12 ?

  23. Jenijo Macfarlane says:

    Use a calculator to find the values of the following, round your answers to 2 decimal places.

    √65 (b) √3 (c) √16 (d) √24 (e) √2 I have tried to do this but I just cant get it to work because I know how to do the square root questions without the calculator but I cant seem to find the formulae for this ?

  24. Jenijo Macfarlane says:

    sorry to make my last question clearer. when I am typing in calculator
    root 65 = the answer it is giving me is :- root 65 on the calculator
    root 3 = the answer it is give me is :- root 3 on the calculator
    root 16 = the answer it give me is :- root 4 on calculator ( I know this is right why does it give me the answer for this one but not the others)
    root 24 = the answer it gives me is 2 root 6 ( I don’t know how to set this out ) as the answer does not look familiar.
    hope that makes a bit more sense.

    • Ah I see yes, there should be a button on your calculator that either says “change” or “s-d” it’s on the right hand side near the AC button. If you hit that then it should give you a decimal.

      If not then it must be a calculator I am unfamiliar with. I would be able to work it out in person.

      Let me know if that helps.

      • Jenijo says:

        Hi Mr MacIntyre
        Thank you for getting back. thats what I needed to do…have pressed the sd button now and its working out in decimal places thanks very much.

  25. Kyle says:

    Hi,
    I noticed that the Blue Course – Block E revison is missing a question 2, is that supposed to happen?

  26. Ciaran says:

    Hi mr macintyre what is a prime number

  27. Kyle says:

    Hi,
    How would you make 12 and 1/2% into a fraction?

  28. Jodie says:

    Hi,
    See for 1/2x-1=1/5x-4,
    I know you said times the bottom by the bigger number
    I know it’s five but I’m confused about what would happen to the 2
    And what the outcome would be,
    Could you please help me.

  29. Kayleigh Bell says:

    Hi I am having trouble with probability it is BE2.3 question 1 b) what does it mean by square numbers?

  30. Kayleigh Bell says:

    what does it go up in?

  31. Kayleigh Bell says:

    never mind I got it.

  32. Teigan says:

    How would you put 12.5% into an equivalent fraction

  33. Kirsty B. says:

    Hi
    how do find all the square roots of 9?

  34. Abbey says:

    Hi
    I am struggling a bit with be1.4 question 4

  35. Ciaran says:

    I am struggling with be1.4 as well

  36. Ciaran says:

    Never mind I’ve got it

  37. abbey says:

    also question 5 on be1.4

  38. Kirsty B. says:

    never mind I figured it out

  39. Ciaran says:

    Q4 and 5

  40. abbey says:

    x/5 = 10

  41. Kirsty B. says:

    hello
    for BE4.6 its asking you to find the square roots of negative numbers, but negative numbers don’t have a square root, so would I change the negative to a positive and then find the square root of that?

  42. Jenijo Macfarlane says:

    Hi Mr. Macintyre I was just doing BE1.4 Q4 (b) I know that x/5=10 is x=50 because you multiply by 5 but on (b) its 6/x= -2 so if x is on the bottom what do you do ?

  43. Teigan says:

    I got confused at 5 1/2 – 2 3/5
    I done 5-2=3
    then I done 1/2 – 3/5
    I got 5/10 – 6/10
    = -1/10 and was just wondering if that is right so would the answer be 3 -1/10 because I haven’t seen negatives in this type of sum before

  44. Jenijo Macfarlane says:

    oh ok I thought it was 6/x= -2
    x= -2 times 6
    so x= -12 ?

  45. abbey says:

    hi
    i was wondering for bc3.2 q1 what does the part tally mean does it mean the same as mark

  46. Jenijo Macfarlane says:

    if it was 1/3 x+2=1+1/4x would you be multiplying by four because its the bigger number ?

  47. Jenijo Macfarlane says:

    oh yeah I remember now. I am just going over the equations right now, I know how to do the longer ones but see if its just 5x= -15 do you just do – 15 takeaway 5 ?

  48. Jenijo Macfarlane says:

    you know how when you bring a negative over to the other side it becomes a positive does that mean if you bring a positive over to the other side it becomes a negative ?

  49. Jenijo Macfarlane says:

    so it would be x = – 3 ?

  50. Jenijo Macfarlane says:

    sorry for asking so many questions ! but see on BE1.4 Q 4. (e) 10+2/3x= -8 how would you do that because I can do a, b, c and d but I cant do e or f ? thanks.

  51. Kayleigh Bell says:

    what would you do for the square root of negative 9?

  52. Jenijo Macfarlane says:

    ok thankyou.

  53. Jenijo Macfarlane says:

    15-3(x+2)=5x+1 would it be
    15-3x-6=5x+1
    what would you the do when gathering the like terms because I didn’t know if because their isn’t a sign infront of the equals sign if it would be 3x – 5x or 3 x +5x .

  54. Jenijo Macfarlane says:

    ok. Thank you
    Evaluate the following expressions, given that

    m = 3 n = 5 p = 6 q = -2 r = -3 t = -6 v = -10
    h) mnv/(t+r-p) that gave me 3x5x-10/-6+-3-6 I am confused about what the signs would be on the bottom bit because its 6+-3 would this just become 6- 3 ?

  55. Jodie says:

    Hi,
    How would you do,
    6+3x/7=2+x/5

  56. Jenijo says:

    For BC3.1 Q3. (b) it asks the median of the stem and leaf diagram, is it 57 ?

  57. Jenijo says:

    Ok thank you.

  58. Jenijo says:

    Thankyou !
    I was just doing this question and i know how to add a cumulative frequency column but i am unsure on finding the median of when its in a table…

    Terry records the number of cars he sells in the 1st week of June.
    Day Frequency
    Mon 3
    Tue 2
    Wed 5
    Thur 6
    Fri 4
    Sat 10
    Would you add the frequency up which would be 30 then divide by 6 cause there is six days ?

  59. Jenijo says:

    oh wait never mind I think you use that formulae for the ,mean ! … but I don’t know how to find the median of that table.
