Question

What is in expanded form?

Answer

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

is in the ones place, so we multiply by .

$9\times1=9$

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 $\frac{1}{100}$ .

$5\times\frac{1}{100}=.05$

Then we add the products together.

$\frac{\begin{array}[b]{r}9.00\ +\ .20\ .05 \end{array}}{ \ \ \space9.25}$
