Multiply 2-digit and 1-digit numbers worksheet for math practice.

Explanation:
We need to multiply each 2-digit number by the 1-digit number below it. Let’s go row by row and compute each product carefully.

Row 1:
- 49 × 4 = (40 × 4) + (9 × 4) = 160 + 36 = 196
- 22 × 2 = (20 × 2) + (2 × 2) = 40 + 4 = 44
- 52 × 3 = (50 × 3) + (2 × 3) = 150 + 6 = 156
- 27 × 5 = (20 × 5) + (7 × 5) = 100 + 35 = 135

Row 2:
- 75 × 4 = (70 × 4) + (5 × 4) = 280 + 20 = 300
- 72 × 2 = (70 × 2) + (2 × 2) = 140 + 4 = 144
- 96 × 5 = (90 × 5) + (6 × 5) = 450 + 30 = 480
- 57 × 3 = (50 × 3) + (7 × 3) = 150 + 21 = 171

Row 3:
- 52 × 9 = (50 × 9) + (2 × 9) = 450 + 18 = 468
- 17 × 6 = (10 × 6) + (7 × 6) = 60 + 42 = 102
- 35 × 7 = (30 × 7) + (5 × 7) = 210 + 35 = 245
- 53 × 8 = (50 × 8) + (3 × 8) = 400 + 24 = 424

Row 4:
- 71 × 6 = (70 × 6) + (1 × 6) = 420 + 6 = 426
- 86 × 9 = (80 × 9) + (6 × 9) = 720 + 54 = 774
- 79 × 8 = (70 × 8) + (9 × 8) = 560 + 72 = 632
- 64 × 7 = (60 × 7) + (4 × 7) = 420 + 28 = 448

Let me double-check a few tricky ones:
- 86 × 9: 86 × 10 = 860, minus 86 = 774 ✔
- 79 × 8: 80 × 8 = 640, minus 8 = 632 ✔
- 64 × 7: 60×7=420, 4×7=28 → 448 ✔

All calculations are correct.

Final Answer:
196, 44, 156, 135, 300, 144, 480, 171, 468, 102, 245, 424, 426, 774, 632, 448
