Question

Write the following as decimal.

$\frac{18}{5}$

Answer 1

In $\frac{18}{5}$, the denominator is $5$.

We will change the denominator to $10.$

Multiply the numerator and denominator by $2$. $\left(\because 10÷5=2\right)$

$\therefore \frac{18}{5}=\frac{18\times 2}{5\times 2}=\frac{36}{10}$

$=\frac{30+6}{10}=\frac{30}{10}+\frac{6}{10}$

$=3+0.6=3.6$ $\left(\because \frac{1}{10}=0.1\right)$

Hence, the decimal form of $\frac{18}{5}$$=3.6$
