Let’s solve each problem step by step. Remember: when you divide a number by 10, 100, or 1000, the decimal point moves to the left — one place for 10, two places for 100, three places for 1000.
But here, we’re given the result and need to find what was divided (or what divisor was used). So we’ll think backwards.
---
Problem 1:
___ ÷ 100 = 4.58
→ To get back to the original number, multiply 4.58 × 100 =
458
Problem 2:
422 ÷ ___ = 4.22
→ How many times do we divide 422 to get 4.22?
Move decimal in 422 two places left → 4.22 → so divide by
100
Problem 3:
637 ÷ ___ = 6.37
→ Move decimal two places left → divide by
100
Problem 4:
___ ÷ 100 = 6.26
→ Multiply 6.26 × 100 =
626
Problem 5:
672 ÷ ___ = 67.2
→ Move decimal one place left → divide by
10
Problem 6:
898 ÷ ___ = 89.8
→ Move decimal one place left → divide by
10
Problem 7:
___ ÷ 1000 = 0.372
→ Multiply 0.372 × 1000 =
372
Problem 8:
___ ÷ 10 = 30.3
→ Multiply 30.3 × 10 =
303
Problem 9:
___ ÷ 1000 = 0.431
→ Multiply 0.431 × 1000 =
431
Problem 10:
826 ÷ ___ = 0.826
→ Move decimal three places left → divide by
1000
Problem 11:
62 ÷ ___ = 6.2
→ Move decimal one place left → divide by
10
Problem 12:
___ ÷ 100 = 3.55
→ Multiply 3.55 × 100 =
355
Problem 13:
972 ÷ ___ = 9.72
→ Move decimal two places left → divide by
100
Problem 14:
46 ÷ ___ = 0.046
→ Move decimal three places left → divide by
1000
Problem 15:
84 ÷ ___ = 0.084
→ Move decimal three places left → divide by
1000
Problem 16:
___ ÷ 100 = 1.42
→ Multiply 1.42 × 100 =
142
