Question

Write the following as decimal.

$12\frac{3}{10}$

Answer 1

$12\frac{3}{10}$ means we have,

$12+\frac{3}{10}=10+2+\frac{3}{10}$

$\Rightarrow 1\mathrm{tens},2\mathrm{ones}\mathrm{and}3\mathrm{tenths}$

$$\begin{gathered} \therefore 12\frac{3}{10}=10+2+\frac{3}{10}=12+0.3 \\ =12.3 \end{gathered}$$ $\left(\because \frac{1}{10}=0.1\right)$

Hence, the decimal form of $12\frac{3}{10}=12.3$
