$\sf\frac{5}{7} \times \frac{21}{15} \div \frac{8}{7}$

$\boxed {\boxed{ { \color{aqua}{ \bold{ \underline{ Solution:-}}}}}}$

$\large \sf\frac{5}{7} \times \frac{21}{15} \div \frac{8}{7}$

$\sf\twoheadrightarrow\frac{5}{7} \times \bigg(\frac{21}{15} \div \frac{8}{7} \bigg)$

$\large \sf \twoheadrightarrow \: \frac{5}{7} \times \bigg( \frac{ \cancel{21}}{ \cancel{15}} \div \frac{8}{7} \bigg)$

$\large \sf \twoheadrightarrow \: \frac{5}{7} \times \bigg( \frac{7}{5} \div \frac{7}{8} \bigg)$

$\large \sf \twoheadrightarrow \frac{5}{7} \times \bigg( \frac{7 \times 7}{5 \times 8} \bigg)$

$\large \sf \twoheadrightarrow \frac{ \cancel5}{ \cancel{7}} \times \frac{ \cancel{49}}{ \cancel{40} }$

$\ \sf \: \twoheadrightarrow \ \frac{5}{1} \times \frac{7}{8} \\ \\ \sf \twoheadrightarrow \: \frac{35}{8} \: \: \: \: \: \: \: \:$
