Do the ratios 10:9 and 17:15 form a proportion?
KIM [24]

Answer:

Nope! these ratios do not form a proportion

Step-by-step explanation:

if you use a calculator to divide 10/9, you get 1.111 repeating.

if you use a calculator to divide 17/15, you get 1.133 repeating.

<em>since 1.111 does not equal 1.113, </em><em>these ratios are not proportional. </em>
