Answer:

NOTE: To convert a percent to a fraction, we have to remove the percent sign and divide the given number by 100.

1. 10% = 10/100 = 0.1

0.1/1 × 10/10

= 1/10

3. 100% = 100/100 = 1

5. 50% = 50/100 = 0.5

0.5/1 × 10/10

= 5/10 = 1/2

7. 40% = 40/100= 0.4

0.4/1 × 10/10

= 4/10 = 2/5

9. 25% = 25/100 = 0.25

0.25/1 × 100/100

= 25/100 = 1/4

NOTE: To change a percent to a decimal we divide by 100. This is the same as moving the decimal point two places to the left. For example, 15% is equivalent to the decimal 0.15.

2. 10% = 10 over 100

10% = 10/100

10 ÷ 100 = 0.1

4. 25% = 25 over 100

25% = 25/100

25 ÷ 100 = 0.25

6. 100% = 100 over 100

100% = 100/100

100 ÷ 100 = 1

8. 50% = 50 over 100

50% = 50/100

50 ÷ 100 = 0.5

10. 40% = 40 over 100

40% = 40/100

40 ÷ 100 = 0.4

NOTE: To get the percentage: Rate × Base = Percentage.

11-12. 5% × 300 = 15

13-14. 15% × 200 = 30

15-16. 20% × 500 = 100

17-18. 30% × 600 = 180

19-20. 50% × 100 = 50

21-25. x%/100% = 36/60

therefore x is 60%
