Question

Divide 33 photos into two groups so the ratio is 4 to 7

Answer 1

4:7
4x:7x

4x+7x=11x

11x=33
x=3

4x3=21
7x3=21 so 12 and 21 are in a ratio and add up to 33 hope i helped

Answer 2

33 photos in a 4x to 7x ratio

4x + 7x = 33
11x = 33
x = 3

33 photos can be put in a 4(3) to 7(3) ratio

which is a 12 to 21 ratio

so 12 photos on one side, and 21 on the other side to get the ratio of 4 to 7

Note:
a(b) = ab = a x b = a times b
