Let’s solve each multiplication problem step by step. We’re multiplying 3-digit numbers by 2-digit numbers, all of which are multiples of 3 (like 111, 114, etc.) — but that doesn’t change how we multiply. We’ll just do regular multiplication.
We’ll go row by row, left to right.

First Row:
1.
113 × 29
Break it down:
- 113 × 20 = 2260
- 113 × 9 = 1017
- Add them: 2260 + 1017 =
3277
2.
114 × 18
- 114 × 10 = 1140
- 114 × 8 = 912
- Add: 1140 + 912 =
2052
3.
112 × 47
- 112 × 40 = 4480
- 112 × 7 = 784
- Add: 4480 + 784 =
5264
4.
116 × 16
- 116 × 10 = 1160

13.
142 × 58
- 142 × 50 = 7100
- 142 × 8 = 1136
- Add: 7100 + 1136 =
8236
14.
141 × 18
- 141 × 10 = 1410
- 141 × 8 = 1128
- Add: 1410 + 1128 =
2538
15.
147 × 19
- 147 × 10 = 1470

Fifth Row:
17.
144 × 51
- 144 × 50 = 7200
- 144 × 1 = 144
- Add: 7200 + 144 =
7344
18.
144 × 42
- 144 × 40 = 5760
- 144 × 2 = 288
- Add: 5760 + 288 =
6048
19.
143 × 36
- 143 × 30 = 4290
- 143 × 6 = 858
- Add: 4290 + 858 =
5148
20.
142 × 40
This one is easy — just add a zero and multiply by 4:
- 142 × 4 = 568 → then add zero →
5680
