Question

The product of two fraction is $9$. If one of the fraction is $2\frac{1}{7}$, find the other fraction.

Answer 1

Let $\frac{a}{b}$ & $\frac{p}{q}$ be two fraction.

Given $[\frac{a}{b}\times \frac{p}{q}]=9$--(1)

and $[\frac{a}{b}=\frac{15}{7}]$

then$\left(\frac{p}{q}\right)=9\times \frac{7}{15}$ =$\frac{21}{5}$

$[\frac{p}{q}=4\frac{1}{5}]$
