Question

Solve : $2\frac{2}{7}$ of $15\frac{3}{4}\times 2\frac{1}{4}+\frac{4}{7}$ of $2\frac{5}{8}$.

Answer 1

$2\frac{2}{7}of15\frac{3}{4}\times 2\frac{1}{4}+\frac{4}{7}of2\frac{5}{8}$

$=\frac{16}{7}of\frac{63}{4}\times \frac{9}{4}+\frac{4}{7}of\frac{21}{8}$

$=(\frac{16}{7}\times \frac{63}{4}\times \frac{9}{4})+(\frac{4}{7}\times \frac{21}{8})$

$=9\times 9+\frac{3}{2}$

$=81+\frac{3}{2}$

$=\frac{81\times 2+3}{2}$

$=\frac{165}{2}$
