Question

Evaluate the following:

$\frac{8}{21}÷4$

Answer 1

$\frac{8}{21}÷4$$=$$\frac{8}{21}÷\frac{4}{1}$ ( Replace the $÷$ sign into $\times$ and take the reciprocal of $4$)

$=\frac{8}{21}\times \frac{1}{4}$ (Cancel out the common factor)

$=\frac{2}{21}$

Hence, $\frac{2}{21}$ is the required solution.
