Step-by-step solution for: Multiplying 2-Digit by 1-Digit Numbers (A)
Let’s solve each multiplication problem step by step. We’ll multiply the 2-digit number by the 1-digit number, just like you do on paper — starting from the ones place and moving to the tens place.
---
First Row:
1. 72 × 2
→ 2 × 2 = 4 (ones)
→ 2 × 7 = 14 (tens) → write down 14
→ So, 72 × 2 = 144
2. 31 × 8
→ 8 × 1 = 8 (ones)
→ 8 × 3 = 24 (tens) → write down 24
→ So, 31 × 8 = 248
3. 73 × 4
→ 4 × 3 = 12 → write 2, carry 1
→ 4 × 7 = 28 + 1 = 29
→ So, 73 × 4 = 292
4. 95 × 9
→ 9 × 5 = 45 → write 5, carry 4
→ 9 × 9 = 81 + 4 = 85
→ So, 95 × 9 = 855
5. 11 × 7
→ 7 × 1 = 7 (ones)
→ 7 × 1 = 7 (tens)
→ So, 11 × 7 = 77

Second Row:
6. 65 × 9
→ 9 × 5 = 45 → write 5, carry 4
→ 9 × 6 = 54 + 4 = 58
→ So, 65 × 9 = 585
7. 74 × 4
→ 4 × 4 = 16 → write 6, carry 1
→ 4 × 7 = 28 + 1 = 29
→ So, 74 × 4 = 296
8. 11 × 9
→ 9 × 1 = 9 (ones)
→ 9 × 1 = 9 (tens)
→ So, 11 × 9 = 99
9. 24 × 5
→ 5 × 4 = 20 → write 0, carry 2
→ 5 × 2 = 10 + 2 = 12
→ So, 24 × 5 = 120
10. 68 × 9
→ 9 × 8 = 72 → write 2, carry 7
→ 9 × 6 = 54 + 7 = 61
→ So, 68 × 9 = 612
---
Third Row:
11. 99 × 9
→ 9 × 9 = 81 → write 1, carry 8
→ 9 × 9 = 81 + 8 = 89
→ So, 99 × 9 = 891
12. 35 × 3
→ 3 × 5 = 15 → write 5, carry 1
→ 3 × 3 = 9 + 1 = 10
→ So, 35 × 3 = 105
13. 56 × 9
→ 9 × 6 = 54 → write 4, carry 5
→ 9 × 5 = 45 + 5 = 50
→ So, 56 × 9 = 504
14. 52 × 4
→ 4 × 2 = 8 (ones)
→ 4 × 5 = 20 (tens)
→ So, 52 × 4 = 208
15. 83 × 5
→ 5 × 3 = 15 → write 5, carry 1
→ 5 × 8 = 40 + 1 = 41
→ So, 83 × 5 = 415
