Let's solve this step by step. The task is to
estimate the product of each multiplication problem. Estimating means rounding the numbers to simpler values (usually to the nearest ten or hundred) and then multiplying.

1. 96 × 13
- Round 96 → 100
- Round 13 → 10
- Estimate: 100 × 10 =
1,000
✔ Answer:
100 × 10 = 1,000
---
2. 64 × 55
- Round 64 → 60
- Round 55 → 60
- Estimate: 60 × 60 =
3,600
✔ Answer:
60 × 60 = 3,600

3. 82 × 57
- Round 82 → 80
- Round 57 → 60
- Estimate: 80 × 60 =
4,800
✔ Answer:
80 × 60 = 4,800
---
4. 91 × 23
- Round 91 → 90
- Round 23 → 20
- Estimate: 90 × 20 =
1,800
✔ Answer:
90 × 20 = 1,800

5. 132 × 38
- Round 132 → 130
- Round 38 → 40
- Estimate: 130 × 40 =
5,200
✔ Answer:
130 × 40 = 5,200
---
6. 289 × 69
- Round 289 → 300
- Round 69 → 70
- Estimate: 300 × 70 =
21,000
✔ Answer:
300 × 70 = 21,000
---
✔ Final Answers:
1.
100 × 10 = 1,000
2.
60 × 60 = 3,600
3.
80 × 60 = 4,800
4.
90 × 20 = 1,800
5.
130 × 40 = 5,200
6.
300 × 70 = 21,000

Tip: Estimation helps check if your exact answer is reasonable. For example, if you calculate 96 × 13 exactly and get something like 1,248, the estimate of 1,000 shows it's in the right ballpark!
