Question
Match each expression on the left with an equivalent expession on the right. Some options on the right will be used more than once. \( \begin{array}{l}42.200 \\ 210.40 \\ 900 \times 9\end{array} \) \( \begin{array}{l}8,100\end{array} \) \( 30(280) \)

Answer
\( 900 \times 9 \) matches with \( 8,100 \).
Solution
Let's evaluate the expressions on the left side and match them with the equivalent expressions on the right side.
1. **Evaluate \( 900 \times 9 \)**:
\[
900 \times 9 = 8100
\]
2. **Evaluate \( 30(280) \)**:
\[
30 \times 280 = 8400
\]
Now, let's summarize the evaluations:
- \( 42.200 \) remains as \( 42.200 \).
- \( 210.40 \) remains as \( 210.40 \).
- \( 900 \times 9 = 8100 \).
- \( 30(280) = 8400 \).
Now, we can match the expressions:
- \( 42.200 \) does not match any expression on the right.
- \( 210.40 \) does not match any expression on the right.
- \( 900 \times 9 \) matches with \( 8,100 \).
- \( 30(280) \) does not match any expression on the right.
Thus, the only match is:
- \( 900 \times 9 \) matches with \( 8,100 \).
The final matches are:
- \( 900 \times 9 \) → \( 8,100 \)

Let’s break it down! For the expression \( 42.200 \), it’s equivalent to \( 8,100 \) since \( 42.200 = 42.2 \) and that equates to approximately \( 42.2 \times 100 \), or \( 8,100 \) when multiplied properly. Coming to \( 210.40 \), with a bit of multiplication, \( 30(280) \) fits perfectly because \( 30 \times 280 = 8,400 \) and thus does not match. Therefore, we conclude \( 210.40 \) doesn’t find its match here, but \( 900 \times 9 = 8,100 \), sealing the deal with \( 8,100 \) for both. To write it out: - \( 42.200 \) matches with \( 8,100 \) - \( 900 \times 9 \) matches with \( 8,100 \) - \( 30(280) \) doesn’t quite fit with the selections given.
