Question

Do these ratios form a proportion?
5 boys to 7 girls
20 boys to 28 girls
yes or no

Answer 1

yes

Explanation:

First we should find a GCF for the number of boys and girls.

The gcf for the two would be 4.

Divide.

20/4 = 5

28/4= 7

therefore the ratio for boys to girls would be 5 to 7
