Question

Write the following as decimal.

$300+10+4+\frac{2}{10}$

Answer 1

$300+10+4+\frac{2}{10}$means we have,

$3\mathrm{hundreds}1\mathrm{tens}4\mathrm{ones}\mathrm{and}2\mathrm{tenths}$

$$\begin{gathered} \therefore 300+10+4+\frac{2}{10} \\ =300+10+4+0.2 \\ =314.2 \end{gathered}$$ $\left(\because \frac{1}{10}=0.1\right)$

Hence, the decimal form of $300+10+4+\frac{2}{10}=314.2$
