Question

Express the following ratios in simplest form:

$\frac{1}{15}:\frac{1}{25}$

Answer 1

Given ratio is $\frac{1}{15}:\frac{1}{25}$

Since it is fraction, then multiply both terms by the LCM of denominator $15$ and $25$

LCM of $15$ and $25$ is $75$

Therefore,

$\frac{1}{15}\times 75:\frac{1}{25}\times 75=5:3$

Hence, simplest form of $\frac{1}{15}:\frac{1}{25}$ is $5:3$
