Decimal to Percent Conversion Practice Worksheet

To change a decimal to a percent, you multiply the decimal by 100 and add the % sign.
This is the same as moving the decimal point two places to the right.

Let’s go through each problem one by one:

1. 0.23 → move decimal two places right → 23%
2. 0.54 → 54%
3. 0.34 → 34%
4. 0.82 → 82%
5. 0.13 → 13%
6. 0.99 → 99%
7. 0.5 → 50% (because 0.5 = 0.50)
8. 0.7 → 70% (because 0.7 = 0.70)
9. 0.6 → 60% (because 0.6 = 0.60)
10. 0.19 → 19%
11. 0.05 → 5%
12. 0.09 → 9%
13. 0.07 → 7%
14. 0.66 → 66%
15. 1.23 → 123% (move decimal two places: 1.23 → 123)
16. 1.88 → 188%
17. 0.13 → 13% (same as #5)
18. 0.8 → 80%
19. 3.00 → 300%
20. 0.11 → 11%

All answers are checked by multiplying the decimal by 100 or shifting the decimal point two places right — both methods give the same result.
