Question

Write the following as decimal.

$\frac{5}{2}$

Answer 1

In $\frac{5}{2}$, the denominator is $2$.

We will change the denominator to $10.$

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

$\therefore \frac{5}{2}=\frac{5\times 5}{2\times 5}=\frac{25}{10}$

$=\frac{20+5}{10}=\frac{20}{10}+\frac{5}{10}$

$=2+0.5$ $\left(\because \frac{1}{10}=0.1\right)$

$=2.5$

Hence, the decimal form of $\frac{5}{2}$$=2.5$
