Question

Write three equivalent ratios for the following:

$5:9=\_\_\_=\_\_\_=\_\_\_$

Answer 1

Equivalent ratios are the ratios obtained by multiplying with the same number in both the given terms.

Given ratios is $5:9$

Equivalent ratio of $5:9$ $=(5\times 2):(9\times 2)=10:18$ ( Multiply with $2$ in both terms)

Similarly $(5\times 3):(9\times 3)=15:27$ ( Multiply with $3$ in both terms)

and, $(5\times 4):(9\times 4)=20:36$ ( Multiply with $4$ in both terms)

Hence, three equivalent ratio of $5:9$ is $10:18,15:27,20:36$
