Let’s solve each problem step by step. Remember: when dividing fractions, you
flip the second fraction (that’s called finding its reciprocal) and then
multiply.

Problem 1:
2/10 ÷ 3/5
Step 1: Flip the second fraction → 3/5 becomes 5/3
Step 2: Multiply: (2/10) × (5/3) = (2×5)/(10×3) = 10/30
Step 3: Simplify: 10/30 = 1/3
✔ Answer:
1/3

Problem 2:
25/27 ÷ 4/3
Step 1: Flip 4/3 → becomes 3/4
Step 2: Multiply: (25/27) × (3/4) = (25×3)/(27×4) = 75/108
Step 3: Simplify — divide numerator and denominator by 3 → 25/36
✔ Answer:
25/36
---
Problem 3:
1/5 ÷ 3/2
Step 1: Flip 3/2 → becomes 2/3
Step 2: Multiply: (1/5) × (2/3) = 2/15
Step 3: Already simplified.
✔ Answer:
2/15

Problem 4:
1/2 ÷ 9/11
Step 1: Flip 9/11 → becomes 11/9
Step 2: Multiply: (1/2) × (11/9) = 11/18
Step 3: Already simplified.
✔ Answer:
11/18

Problem 5:
5/2 ÷ 10/7
Step 1: Flip 10/7 → becomes 7/10
Step 2: Multiply: (5/2) × (7/10) = 35/20
Step 3: Simplify — divide by 5 → 7/4 → or as mixed number: 1 3/4
But since the worksheet uses improper fractions, we’ll leave it as
7/4
✔ Answer:
7/4
---
Problem 6:
30/42 ÷ 5/6
Step 1: Flip 5/6 → becomes 6/5
Step 2: Multiply: (30/42) × (6/5) = (30×6)/(42×5) = 180/210
Step 3: Simplify — divide numerator and denominator by 30 → 6/7
(Or step-by-step: 180÷30=6, 210÷30=7)
✔ Answer:
6/7
---
Problem 7:
7/25 ÷ 13/25
Step 1: Flip 13/25 → becomes 25/13
Step 2: Multiply: (7/25) × (25/13) = (7×25)/(25×13)
Step 3: Cancel out the 25s → 7/13
✔ Answer:
7/13
---
Problem 8:
20/125 ÷ 5/25
Step 1: Flip 5/25 → becomes 25/5
Step 2: Multiply: (20/125) × (25/5) = (20×25)/(125×5) = 500 / 625
Step 3: Simplify — divide numerator and denominator by 125 → 4/5
(Check: 500÷125=4, 625÷125=5)
✔ Answer:
4/5
---
Problem 9:
36/5 ÷ 6/5
Step 1: Flip 6/5 → becomes 5/6
Step 2: Multiply: (36/5) × (5/6) = (36×5)/(5×6)
Step 3: Cancel out the 5s → 36/6 = 6
✔ Answer:
6
---
Problem 10:
12/13 ÷ 9/7
Step 1: Flip 9/7 → becomes 7/9
Step 2: Multiply: (12/13) × (7/9) = (12×7)/(13×9) = 84/117
Step 3: Simplify — divide numerator and denominator by 3 → 28/39
✔ Answer:
28/39
---
Problem 11:
75/19 ÷ 100/19
Step 1: Flip 100/19 → becomes 19/100
Step 2: Multiply: (75/19) × (19/100) = (75×19)/(19×100)
Step 3: Cancel out the 19s → 75/100
Step 4: Simplify — divide by 25 → 3/4
✔ Answer:
3/4
---
Problem 12:
100/60 ÷ 2/30
Step 1: Flip 2/30 → becomes 30/2
Step 2: Multiply: (100/60) × (30/2) = (100×30)/(60×2) = 3000 / 120
Step 3: Simplify — divide numerator and denominator by 60 → 50/2 = 25
(Or: 3000 ÷ 120 = 25)
✔ Answer:
25
