MULTIPLICATION PROBLEMS:
7. 986 × 72
- 986 × 2 = 1972
- 986 × 70 = 69020
- 1972 + 69020 = 70992
- Answer: 70992
8. 568 × 65
- 568 × 5 = 2840
- 568 × 60 = 34080
- 2840 + 34080 = 36920
- Answer: 36920
9. 1234 × 96
- 1234 × 6 = 7404
- 1234 × 90 = 111060
- 7404 + 111060 = 118464
- Answer: 118464
DIVISION PROBLEMS:
10. 1920 ÷ 60
- 60 goes into 192 three times (60 × 3 = 180)
- 192 - 180 = 12
- Bring down 0: 120
- 60 goes into 120 two times (60 × 2 = 120)
- 120 - 120 = 0
- Answer: 32
11. 4617 ÷ 19
- 19 goes into 46 two times (19 × 2 = 38)
- 46 - 38 = 8
- Bring down 1: 81
- 19 goes into 81 four times (19 × 4 = 76)
- 81 - 76 = 5
- Bring down 7: 57
- 19 goes into 57 three times (19 × 3 = 57)
- 57 - 57 = 0
- Answer: 243
12. 5494 ÷ 82
- 82 goes into 549 six times (82 × 6 = 492)
- 549 - 492 = 57
- Bring down 4: 574
- 82 goes into 574 seven times (82 × 7 = 574)
- 574 - 574 = 0
- Answer: 67
Final Answer:
