Question

Write the short form of the following as a decimal number.

$500+60+7+0.9+0.03+0.004$

Answer 1

We have,

$500+60+7+0.9+0.03+0.004=\left(5\times 100\right)+\left(6\times 10\right)+\left(7\times 1\right)+\left(9\times \frac{1}{10}\right)+\left(3\times \frac{1}{100}\right)+\left(4\times \frac{1}{1000}\right)$

Here, the place value of$5=500$, the place value of$6=60$, the place value of$7=7$, the place value of$9=\frac{9}{10}$, the place value of$3=\frac{3}{100}$, and the place value of $4=\frac{4}{1000}$

So, In decimal form, $5$ is at hundreds, $6$is at tens place, $7$is at ones,$9$ is at tenths,$3$ is at hundredths, and $4$is at thousandths place.

Hence, the decimal form is $567.934$
