Question

Help me please

Answer 1

Use a common denominator to determine whether the ratios form a proportion.

6 : 15 and 30 : 80

A.
Yes. They form a proportion.

B.
No. They do not form a proportion.

Answer 2

two ratios are only proportional if they can both be reduced to same ratio

6/15 = 2/5

30/80 = 3/8

obviously not the same so they are not proportional
