  2. squares : total shapes = 3:8
    so squares : circles = 3:5 , because (5+3 = 8)
    = 3x : 5x

    given: 5x = 25
    x = 5

    so we had 3x or 15 squares and
    5x or 25 circles

    15 squares
    25 circles
    40 total,
    note : squares : total = 15:40 = 3 : 8

  3. No, don't listen to me. I read it wrong, I think. I believe this can help you solve it:

    3:8 (squares to total) + x:8 (circles to total) = 8/8 or 1/1
    What is "x"?

    What number (n) multiplied by "x" equals 25 (amount of circles)?
    x:8 * n/n = 25/??

    Take "n" and multiply it by 3:8, like how you did with the previous problem.
    3:8 * n/n = ??/??

    The numerator should be how many squares there are.

    I'm sorry if this is incorrect or just made no sense at all.
