Let's solve each problem step by step. The key concept here is
dividing decimals by 10, 100, and 1000.
When you divide a number by:
-
10, move the decimal point
1 place to the left
-
100, move the decimal point
2 places to the left
-
1000, move the decimal point
3 places to the left
We'll go through each row and fill in the blanks.

Left Column:
1.
43.4 ÷ 10 = ?
Move decimal 1 place left →
4.34
2.
637 ÷ ? = 6.37
637 → 6.37 means decimal moved 2 places left → divided by
100
3.
45 ÷ ? = 0.045
45 → 0.045 is 3 places left → divided by
1000
4.
65 ÷ 100 = ?
Move decimal 2 places left →
0.65
5.
? ÷ 100 = 1.72
To reverse division by 100, multiply 1.72 × 100 =
172
6.
725 ÷ ? = 0.725
725 → 0.725 is 3 places left → divided by
1000
7.
? ÷ 10 = 42.9
Multiply 42.9 × 10 =
429
8.
999 ÷ ? = 99.9
999 → 99.9 is 1 place left → divided by
10
9.
? ÷ 100 = 5.25
Multiply 5.25 × 100 =
525
10.
822 ÷ ? = 82.2
822 → 82.2 is 1 place left → divided by
10

Right Column:
1.
95 ÷ ? = 0.095
95 → 0.095 is 3 places left → divided by
1000
2.
192 ÷ ? = 0.192
192 → 0.192 is 3 places left → divided by
1000
3.
449 ÷ 1000 = ?
Move decimal 3 places left →
0.449
4.
552 ÷ ? = 5.52
552 → 5.52 is 2 places left → divided by
100
5.
372 ÷ 100 = ?
Move decimal 2 places left →
3.72
6.
684 ÷ ? = 68.4
684 → 68.4 is 1 place left → divided by
10
7.
396 ÷ ? = 3.96
396 → 3.96 is 2 places left → divided by
100
8.
445 ÷ ? = 0.445
445 → 0.445 is 3 places left → divided by
1000
9.
? ÷ 1000 = 0.298
Multiply 0.298 × 1000 =
298
10.
94 ÷ ? = 0.094
94 → 0.094 is 3 places left → divided by
1000
