State if each pair of ratios forms a proportion.

Question

1) 4/2 20 6 and
2) a and 18 8

Answer 1

1) The pair of ratios 4/2 and 20/6 forms a proportion because when you simplify both ratios, you get 2/1 and 10/3, which are equivalent.

2) The pair of ratios a/18 and 8/18 does not form a proportion because the denominators are the same, but the numerators are different. So, the ratios are not equivalent.

Answer 2

3/2 and 18/8 State if each pair of ratios forms a proportion.

Answer 3

The pair of ratios 3/2 and 18/8 forms a proportion because when you simplify both ratios, you get 1.5 and 2.25, which are equivalent.
