Question

Match the standard form of numbers to their expanded forms.

• A. 4000 + 100 + 90
• B. 20000 + 70 + 2
• C. 500 + 40 + 9

Answer 1

Let's place the digits under the place value chart.
1. 500 + 40 + 9

$\begin{array}{ccc}H& T& O\\ 5& 4& 9\end{array}$

Thus, the standard form is 549.

2. 4000 + 100 + 90 + 0

$\begin{array}{cccc}Th& H& T& O\\ 4& 1& 9& 0\end{array}$

Thus, the standard form is 4,190.

3. 20000 + 0000 + 000 + 70 + 2

$\begin{array}{ccccc}TTh& Th& H& T& O\\ 2& 0& 0& 7& 2\end{array}$

Thus, the standard form is 20,072.
