I will solve the multiplication problems on this worksheet. The task is to perform 3x2 multiplication (three-digit number multiplied by a two-digit number) with and without regrouping.
Let me solve each problem one by one:
1. 230 × 11
= 230 × (10 + 1)
= 2300 + 230
= 2530
2. 242 × 13
= 242 × (10 + 3)
= 2420 + 726
= 3146
3. 333 × 24
= 333 × (20 + 4)
= 6660 + 1332
= 7992
4. 657 × 10
= 6570 (multiplying by 10 simply adds a zero)
5. 436 × 48
= 436 × (40 + 8)
= 17440 + 3488
= 20928
6. 212 × 35
= 212 × (30 + 5)
= 6360 + 1060
= 7420
7. 244 × 12
= 244 × (10 + 2)
= 2440 + 488
= 2928
8. 243 × 43
= 243 × (40 + 3)
= 9720 + 729
= 10449
9. 132 × 15
= 132 × (10 + 5)
= 1320 + 660
= 1980
The completed worksheet with answers would be:
- 230 × 11 = 2530
- 242 × 13 = 3146
- 333 × 24 = 7992
- 657 × 10 = 6570
- 436 × 48 = 20928
- 212 × 35 = 7420
- 244 × 12 = 2928
- 243 × 43 = 10449
- 132 × 15 = 1980
Parent Tip: Review the logic above to help your child master the concept of 3 x 2 multiplication worksheet.
