$4\times10+7\times1+2\times\left(\frac{1}{10}\right)+3\times\left(\frac{1}{100}\right)+6\times\left(\frac{1}{1000}\right)$

Explanation:

When we write a number in expanded form, we multiply each digit by its place value.

is in the tens place, so we multiply by .

$4\times10=40$

is in the ones place, so we multiply by .

$7\times1=7$

is in the tenths place, so we multiply by $\frac{1}{10}$ .

$2\times\frac{1}{10}=.2$

is in the hundredths place, so we multiply by $\frac{1}{100}$ .

$3\times\frac{1}{100}=.03$

is in the thousandths place, so we will multiply by $\frac{1}{1000}$ .

$6\times\frac{1}{1000}=.006$

Then we add the products together.

$\frac{\begin{array}[b]{r}40.000\\7.000\\ +\ .200\\ .030\\.006 \end{array}}{ \ \ \space47.236}$
