Question

The ratio of squares to total number of shapes (squares + circles) is 3:8.

There are 25 circles.

How many squares are there?

Answer 1

What is a ratio equivalent to 3:8?

Answer 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 <b>15 squares</b> and
5x or 25 circles

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

Answer 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.
