Question

Nisha made a mistake when multiplying the two fractions $\frac{7}{9}$ and $\frac{6}{13}$ and got the result $1$ more than the actual correct result. Find the result obtained by Nisha.

Answer 1

Let’s multiply the fractions $\frac{7}{9}$ and $\frac{6}{13}$.
$\frac{7}{9}$ × $\frac{6}{13}$ = $\frac{7\times 6}{9\times 13}$ = $\frac{42}{117}$ = $\frac{14}{39}$

According to the question, Nisha by mistake added $1$ to the above correct result, that is, $\frac{14}{39}$ + $1$ = $\frac{14+39}{39}$ = $\frac{53}{39}$
