Question

Divide the following

$79.74÷3.6$

Answer 1

Solve the division :

We know that $\mathrm{a}÷\mathrm{b}=\mathrm{a}\times \frac{1}{\mathrm{b}}$, where $\mathrm{a}$ and $\mathrm{b}$ are integers.

$$\begin{gathered} 79.74÷3.6 \\ =\frac{7974}{100}÷\frac{36}{10} \\ =\frac{7974}{100}\times \frac{10}{36} \\ =\frac{9\times 886}{100}\times \frac{10}{9\times 4} \end{gathered}$$

$$\begin{gathered} =\frac{886}{10\times 4} \\ =\frac{221.5}{10} \\ =22.15 \end{gathered}$$

Hence the required answer is $22.15$
