Step-by-step solutions:

#### 1. 0.7
- = 7/10 → already simplified
✔ 7/10

#### 2. 0.78
- = 78/100 → simplify by dividing numerator and denominator by 2
→ 39/50
✔ 39/50

#### 3. 0.57
- = 57/100 → cannot be simplified further
✔ 57/100

#### 4. 0.9
- = 9/10 → already simplified
✔ 9/10

#### 5. 0.76
- = 76/100 → divide by 4 → 19/25
✔ 19/25

#### 6. 0.85
- = 85/100 → divide by 5 → 17/20
✔ 17/20

#### 7. 0.48
- = 48/100 → divide by 4 → 12/25
✔ 12/25

#### 8. 0.77
- = 77/100 → cannot be simplified
✔ 77/100

#### 9. 0.53
- = 53/100 → prime, can't simplify
✔ 53/100

#### 10. 0.37
- = 37/100 → prime, can't simplify
✔ 37/100

#### 11. 0.5
- = 5/10 → simplify → 1/2
✔ 1/2

#### 12. 0.42
- = 42/100 → divide by 2 → 21/50
✔ 21/50

#### 13. 0.36
- = 36/100 → divide by 4 → 9/25
✔ 9/25

#### 14. 0.38
- = 38/100 → divide by 2 → 19/50
✔ 19/50

#### 15. 0.7
- Same as #1 → 7/10
✔ 7/10

#### 16. 0.36
- Same as #13 → 9/25
✔ 9/25

#### 17. 0.57
- Same as #3 → 57/100
✔ 57/100

#### 18. 0.1
- = 1/10 → already simplified
✔ 1/10

#### 19. 0.46
- = 46/100 → divide by 2 → 23/50
✔ 23/50

#### 20. 0.16
- = 16/100 → divide by 4 → 4/25
✔ 4/25

🔍 Tips:

- For decimals ending in one digit: denominator is 10.
- Two digits: denominator is 100.
- Always check for simplification using GCD (greatest common divisor).
