Question

Use the estimates to help you choose each correct answer.

14.8(20.7) =
Estimate: 15(20) = 300
1.1(9.8) =
Estimate: 1(10) = 10
72.5(4.9) =
Estimate: 70(5) = 350

Answer 1

Let's calculate each of the products to confirm the estimates provided:

1. **14.8(20.7)**
Estimated: 15(20) = 300
Actual: 14.8 * 20.7 = 306.36

2. **1.1(9.8)**
Estimated: 1(10) = 10
Actual: 1.1 * 9.8 = 10.78

3. **72.5(4.9)**
Estimated: 70(5) = 350
Actual: 72.5 * 4.9 = 355.25

Based on the estimates:
- For 14.8(20.7), the estimate of 300 is close to the actual value of 306.36.
- For 1.1(9.8), the estimate of 10 is very close to the actual value of 10.78.
- For 72.5(4.9), the estimate of 350 is also close to the actual value of 355.25.

All the estimates are reasonable approximations for the actual products.
