Part 1: Multiplication Problems
We'll multiply each number by either 5 or 6:
1.
43 × 5
Break it down:
$ 40 × 5 = 200 $,
$ 3 × 5 = 15 $,
$ 200 + 15 = 215 $
✔ 215
2.
42 × 6
$ 40 × 6 = 240 $,
$ 2 × 6 = 12 $,
$ 240 + 12 = 252 $
✔ 252
3.
65 × 5
$ 60 × 5 = 300 $,
$ 5 × 5 = 25 $,
$ 300 + 25 = 325 $
✔ 325
4.
65 × 6
$ 60 × 6 = 360 $,
$ 5 × 6 = 30 $,
$ 360 + 30 = 390 $
✔ 390
5.
87 × 5
$ 80 × 5 = 400 $,
$ 7 × 5 = 35 $,
$ 400 + 35 = 435 $
✔ 435
6.
78 × 6
$ 70 × 6 = 420 $,
$ 8 × 6 = 48 $,
$ 420 + 48 = 468 $
✔ 468
7.
97 × 5
$ 90 × 5 = 450 $,
$ 7 × 5 = 35 $,
$ 450 + 35 = 485 $
✔ 485
8.
98 × 6
$ 90 × 6 = 540 $,
$ 8 × 6 = 48 $,
$ 540 + 48 = 588 $
✔ 588

Part 2: Division Problems
Now solve the division problems:
1.
15 ÷ 5 = ?
$ 5 × 3 = 15 $ →
✔ 3
2.
45 ÷ 5 = ?
$ 5 × 9 = 45 $ →
✔ 9
3.
18 ÷ 6 = ?
$ 6 × 3 = 18 $ →
✔ 3
4.
42 ÷ 6 = ?
$ 6 × 7 = 42 $ →
✔ 7
5.
20 ÷ 5 = ?
$ 5 × 4 = 20 $ →
✔ 4
6.
55 ÷ 5 = ?
$ 5 × 11 = 55 $ →
✔ 11
7.
36 ÷ 6 = ?
$ 6 × 6 = 36 $ →
✔ 6
8.
54 ÷ 6 = ?
$ 6 × 9 = 54 $ →
✔ 9
