Answer :
To determine which expression has an estimated product of [tex]$45, let's look at the rounded products of each expression:
1. Expression: \(44.7 \times 2.1\)
- Estimated product: 94
2. Expression: \(7.5 \times 8.4\)
- Estimated product: 63
3. Expression: \(8.7 \times 5.28\)
- Estimated product: 46
4. Expression: \(38.1 \times 7.3\)
- Estimated product: 278
From the estimated products, we can see that the closest expression to 45 is \(8.7 \times 5.28\) with an estimated product of 46. Therefore, this expression has an estimated product that is closest to $[/tex]45.
1. Expression: \(44.7 \times 2.1\)
