Question

Write the following as decimal.

$13+\frac{4}{10}$

Answer 1

$13+\frac{4}{10}$ means we have,

$10+3+\frac{4}{10}$

$\Rightarrow 1\mathrm{tens}3\mathrm{ones}\mathrm{and}4\mathrm{tenths}$

$$\begin{gathered} \therefore 13+\frac{4}{10}=10+3+0.4 \\ =13.4 \end{gathered}$$ $\left(\because \frac{1}{10}=0.1\right)$

Hence, the decimal form of $13+\frac{4}{10}=13.4$
