Let's solve each of the conversion problems in the worksheet step by step, using the conversion chart provided:
Conversion Chart:
- 1 minute = 60 seconds
- 1 hour = 60 minutes
- 1 day = 24 hours
- 1 week = 7 days
- 1 month = 28–31 days (we’ll use average or standard values as needed)
- 1 year = 12 months
- 1 decade = 10 years
- 1 century = 10 decades (100 years)

Problem Solutions:
1. 3 minutes = ____ seconds
→ 3 × 60 =
180 seconds
2. 480 minutes = ____ hours
→ 480 ÷ 60 =
8 hours
3. 11 hours = ____ minutes
→ 11 × 60 =
660 minutes
4. 5 days = ____ hours
→ 5 × 24 =
120 hours
5. 12 hours = ____ day
→ 12 ÷ 24 =
0.5 day (or ½ day)
6. 1 day = ____ minutes
→ 24 × 60 =
1440 minutes
7. 4 weeks = ____ days
→ 4 × 7 =
28 days
8. 6 weeks = ____ hours
→ First: 6 × 7 = 42 days
→ Then: 42 × 24 =
1008 hours
9. 1680 hours = ____ weeks
→ First: 1680 ÷ 24 = 70 days
→ Then: 70 ÷ 7 =
10 weeks
10. 1 month (30 days) = ____ weeks
→ 30 ÷ 7 ≈
4.2857 weeks (or about
4.29 weeks, but often rounded to
4.3 weeks)
11. 2 years = ____ months
→ 2 × 12 =
24 months
12. 60 months = ____ years
→ 60 ÷ 12 =
5 years
13. 0.5 year = ____ months
→ 0.5 × 12 =
6 months
14. 3 decades = ____ months
→ 3 × 10 = 30 years
→ 30 × 12 =
360 months
15. 7 decades = ____ years
→ 7 × 10 =
70 years
16. 45 years = ____ decades
→ 45 ÷ 10 =
4.5 decades
17. 1 century = ____ months
→ 100 years × 12 =
1200 months
18. 600 years = ____ centuries
→ 600 ÷ 100 =
6 centuries
19. 390 years = ____ decades
→ 390 ÷ 10 =
39 decades
20. 0.5 century = ____ months
→ 0.5 × 100 = 50 years
→ 50 × 12 =
600 months
21. 5 decades = ____ years
→ 5 × 10 =
50 years
22. 210 months = ____ decades
→ First: 210 ÷ 12 = 17.5 years
→ Then: 17.5 ÷ 10 =
1.75 decades
23. 100 decades = ____ centuries
→ 100 × 10 = 1000 years
→ 1000 ÷ 100 =
10 centuries
24. 2400 years = ____ centuries
→ 2400 ÷ 100 =
24 centuries
