Question

Multiply $2\frac{1}{3}\times 4\frac{3}{5}$ and divides $\frac{5}{7}÷20$

Answer 1

Consider the given expression,

$2\frac{1}{3}\times 4\frac{3}{5}$ and

$2\frac{1}{3}\times 4\frac{3}{5}=\frac{(2\times 3+1)}{3}\times \frac{(5\times 4+1)}{5}$

$=\frac{7}{3}\times \frac{21}{3}=\frac{49}{3}$

And,

$\frac{5}{7}÷20=\frac{\frac{5}{7}}{20}$

$=\frac{5}{7\times 20}=\frac{1}{28}$

Hence $\frac{49}{3},$ $\frac{1}{28}$ are the answer
