Let’s solve each fraction by converting it to a decimal using equivalent fractions. The goal is to rewrite each fraction so the denominator becomes 10, 100, or another power of 10 — that makes turning it into a decimal easy.
We’ll go one by one:
---
1. 15/20
Multiply numerator and denominator by 5 to get denominator 100:
→ (15 × 5) / (20 × 5) = 75/100 =
0.75
---
2. 12/25
Multiply numerator and denominator by 4 to get denominator 100:
→ (12 × 4) / (25 × 4) = 48/100 =
0.48
---
3. 12/25 → Same as above →
0.48
---
4. 1/2
Multiply numerator and denominator by 5 to get denominator 10:
→ (1 × 5) / (2 × 5) = 5/10 =
0.5
---
5. 13/25
Multiply numerator and denominator by 4:
→ (13 × 4) / (25 × 4) = 52/100 =
0.52
---
6. 3/5
Multiply numerator and denominator by 2 to get denominator 10:
→ (3 × 2) / (5 × 2) = 6/10 =
0.6
---
7. 19/50
Multiply numerator and denominator by 2 to get denominator 100:
→ (19 × 2) / (50 × 2) = 38/100 =
0.38
---
8. 17/20
Multiply numerator and denominator by 5 to get denominator 100:
→ (17 × 5) / (20 × 5) = 85/100 =
0.85
---
9. 6/20
Simplify first: divide numerator and denominator by 2 → 3/10 =
0.3
Or multiply by 5: (6×5)/(20×5)=30/100=0.3 → same answer.
---
10. 1/4
Multiply numerator and denominator by 25 to get denominator 100:
→ (1 × 25) / (4 × 25) = 25/100 =
0.25
---
11. 24/25
Multiply numerator and denominator by 4:
→ (24 × 4) / (25 × 4) = 96/100 =
0.96
---
12. 9/25
Multiply numerator and denominator by 4:
→ (9 × 4) / (25 × 4) = 36/100 =
0.36
---
13. 2/5
Multiply numerator and denominator by 2 to get denominator 10:
→ (2 × 2) / (5 × 2) = 4/10 =
0.4
---
14. 7/20
Multiply numerator and denominator by 5 to get denominator 100:
→ (7 × 5) / (20 × 5) = 35/100 =
0.35
---
