Let’s solve each problem step by step.
When you divide a whole number by a unit fraction (like 1/2, 1/3, 1/4, etc.), you’re really asking:
“How many of these fractions fit into the whole number?”
The trick is:
👉
Dividing by a fraction = multiplying by its reciprocal.
So, for example:
3 ÷ 1/4 = 3 × 4/1 = 12
We’ll go through all 30 problems using this rule.
---
1) 3 ÷ 1/4 = 3 × 4 =
12
2) 2 ÷ 1/3 = 2 × 3 =
6
3) 5 ÷ 1/2 = 5 × 2 =
10
4) 1 ÷ 1/5 = 1 × 5 =
5
5) 6 ÷ 1/4 = 6 × 4 =
24
6) 4 ÷ 1/3 = 4 × 3 =
12
7) 5 ÷ 1/2 = 5 × 2 =
10
8) 7 ÷ 1/3 = 7 × 3 =
21
9) 4 ÷ 1/4 = 4 × 4 =
16
10) 6 ÷ 1/3 = 6 × 3 =
18
11) 4 ÷ 1/6 = 4 × 6 =
24
12) 9 ÷ 1/3 = 9 × 3 =
27
13) 3 ÷ 1/5 = 3 × 5 =
15
14) 5 ÷ 1/4 = 5 × 4 =
20
15) 10 ÷ 1/3 = 10 × 3 =
30
Now the second column:
16) 6 ÷ 1/6 = 6 × 6 =
36
17) 4 ÷ 1/5 = 4 × 5 =
20
18) 2 ÷ 1/7 = 2 × 7 =
14
19) 15 ÷ 1/2 = 15 × 2 =
30
20) 7 ÷ 1/4 = 7 × 4 =
28
21) 3 ÷ 1/7 = 3 × 7 =
21
22) 8 ÷ 1/3 = 8 × 3 =
24
23) 2 ÷ 1/12 = 2 × 12 =
24
24) 8 ÷ 1/5 = 8 × 5 =
40
25) 3 ÷ 1/10 = 3 × 10 =
30
26) 5 ÷ 1/4 = 5 × 4 =
20
27) 7 ÷ 1/6 = 7 × 6 =
42
28) 6 ÷ 1/5 = 6 × 5 =
30
29) 11 ÷ 1/6 = 11 × 6 =
66
30) 9 ÷ 1/4 = 9 × 4 =
36
