Question

Proportions- Determine if each pair of ratios forms a proportion. Show all work!

Answer 1

We are given

two ratios  as

First ratio:

$\frac{30}{80}$

we can simplify it

$\frac{3}{8}$

Second ratio:

$\frac{12}{32}$

we can simplify it

$\frac{12}{32}=\frac{4\times 3}{4\times 8}$

we can cancel 4

$\frac{12}{32}=\frac{ 3}{ 8}$

so, both ratios are same

so, they are proportional..........Answer
