Question

Write the following as decimals:
$20+\frac{9}{10}+\frac{4}{100}$

✓

Answer

$20+\frac{9}{10}+\frac{4}{100}$
Convert $\frac{9}{10}$ and $\frac{4}{100}$ into decimals
$\frac{9}{10}$
Mark the decimal point one place from right to left,
$\frac{9}{10}=0.9$
$=\frac{4}{100}$
Mark the decimal point two places from right to left,
$\frac{4}{100}$
$=0.04$
$=20+\frac{9}{10}+\frac{4}{100}$
$=20+0.9+0.04$
$=20.94$
