Question

Write the numbers in decimal expanded form.

$34.221$

Answer 1

Given $34.221$

Here $3$is at tens place, $4$is at ones,$2$ is at tenths, $2$is at hundredths place, and $1$is at the thousandth place.

So, the place value of$3=30$, the place value of$4=4$, the place value of$2=\frac{2}{10}$, the place value of$2=\frac{2}{100}$, and the place value of $1=\frac{1}{1000}$

Thus,

$$\begin{gathered} 34.221=30+4+\frac{2}{10}+\frac{2}{100}+\frac{1}{1000} \\ =30+4+0.2+0.02+0.001 \end{gathered}$$

Hence, the decimal expanded form is $30+4+0.200+0.020+0.001$
