Let’s solve each problem step by step. We’ll convert decimals to fractions and simplify them.
Remember:
- A decimal like 0.5 means “5 tenths” → 5/10 → simplify to 1/2
- For two decimal places, like 0.04, it’s “4 hundredths” → 4/100 → simplify to 1/25
- For mixed numbers like 1.25, write as 1 + 0.25 → 1 + 25/100 → 1 + 1/4 = 5/4 or 1¼ (but we’ll use improper fractions unless told otherwise)
We’ll go one by one:
---
1. 0.5
= 5/10 =
1/2
2. 0.3
= 3/10 → already simplified →
3/10
3. 0.9
= 9/10 → already simplified →
9/10
4. 0.04
= 4/100 =
1/25
5. 0.13
= 13/100 → already simplified →
13/100
6. 0.1
= 1/10 →
1/10
7. 0.25
= 25/100 =
1/4
8. 0.75
= 75/100 =
3/4
9. 0.05
= 5/100 =
1/20
10. 0.7
= 7/10 →
7/10
---
Now the second column:
11. 1.25
= 1 + 0.25 = 1 + 25/100 = 1 + 1/4 = 5/4 →
5/4
12. 1.3
= 1 + 0.3 = 1 + 3/10 = 13/10 →
13/10
13. 1.1
= 1 + 0.1 = 1 + 1/10 = 11/10 →
11/10
14. 1.5
= 1 + 0.5 = 1 + 1/2 = 3/2 →
3/2
15. 1.22
= 1 + 0.22 = 1 + 22/100 = 1 + 11/50 = 61/50 →
61/50
16. 2.3
= 2 + 0.3 = 2 + 3/10 = 23/10 →
23/10
17. 1.43
= 1 + 0.43 = 1 + 43/100 = 143/100 →
143/100
18. 4.15
= 4 + 0.15 = 4 + 15/100 = 4 + 3/20 = 83/20 →
83/20
19. 2.1
= 2 + 0.1 = 2 + 1/10 = 21/10 →
21/10
20. 1.7
= 1 + 0.7 = 1 + 7/10 = 17/10 →
17/10
---
All answers are simplified fractions. Let me double-check a few tricky ones:
- 0.04 → 4/100 → divide numerator and denominator by 4 → 1/25
✔
- 1.22 → 122/100 → divide by 2 → 61/50
✔
- 4.15 → 415/100 → divide by 5 → 83/20
✔
- 0.05 → 5/100 → 1/20
✔
Everything checks out.
Final Answer:
1. 1/2
2. 3/10
3. 9/10
4. 1/25
5. 13/100
6. 1/10
7. 1/4
8. 3/4
9. 1/20
10. 7/10
11. 5/4
12. 13/10
13. 11/10
14. 3/2
15. 61/50
16. 23/10
17. 143/100
18. 83/20
19. 21/10
20. 17/10
