Let’s solve each division problem step by step. All of these are whole-number divisions (no remainders), and many involve simplifying by canceling zeros or using mental math.
We’ll go row by row:
1.
1600 ÷ 80
Cancel one zero: 160 ÷ 8 = 20
✔ So, 1600 ÷ 80 =
20
2.
2100 ÷ 300
Cancel two zeros: 21 ÷ 3 = 7
✔ So, 2100 ÷ 300 =
7
3.
1440 ÷ 90
Cancel one zero: 144 ÷ 9 = 16
(Because 9 × 16 = 144)
✔ So, 1440 ÷ 90 =
16
4.
990 ÷ 90
Cancel one zero: 99 ÷ 9 = 11
✔ So, 990 ÷ 90 =
11
5.
1200 ÷ 100
Cancel two zeros: 12 ÷ 1 = 12
✔ So, 1200 ÷ 100 =
12
6.
350 ÷ 70
Cancel one zero: 35 ÷ 7 = 5
✔ So, 350 ÷ 70 =
5
7.
900 ÷ 100
Cancel two zeros: 9 ÷ 1 = 9
✔ So, 900 ÷ 100 =
9
8.
1190 ÷ 70
Cancel one zero: 119 ÷ 7
7 × 17 = 119 → so 119 ÷ 7 = 17
✔ So, 1190 ÷ 70 =
17
9.
3840 ÷ 40
Cancel one zero: 384 ÷ 4 = 96
(4 × 96 = 384)
✔ So, 3840 ÷ 40 =
96
10.
7000 ÷ 500
Cancel two zeros: 70 ÷ 5 = 14
✔ So, 7000 ÷ 500 =
14
11.
1800 ÷ 300
Cancel two zeros: 18 ÷ 3 = 6
✔ So, 1800 ÷ 300 =
6
12.
480 ÷ 40
Cancel one zero: 48 ÷ 4 = 12
✔ So, 480 ÷ 40 =
12
13.
880 ÷ 110
Cancel one zero: 88 ÷ 11 = 8
✔ So, 880 ÷ 110 =
8
14.
240 ÷ 30
Cancel one zero: 24 ÷ 3 = 8
✔ So, 240 ÷ 30 =
8
15.
9000 ÷ 1000
Cancel three zeros: 9 ÷ 1 = 9
✔ So, 9000 ÷ 1000 =
9
16.
820 ÷ 20
Cancel one zero: 82 ÷ 2 = 41
✔ So, 820 ÷ 20 =
41
17.
4800 ÷ 80
Cancel one zero: 480 ÷ 8 = 60
✔ So, 4800 ÷ 80 =
60
18.
8400 ÷ 600
Cancel two zeros: 84 ÷ 6 = 14
✔ So, 8400 ÷ 600 =
14
19.
760 ÷ 40
Cancel one zero: 76 ÷ 4 = 19
(4 × 19 = 76)
✔ So, 760 ÷ 40 =
19
20.
8400 ÷ 700
Cancel two zeros: 84 ÷ 7 = 12
✔ So, 8400 ÷ 700 =
12
