My answers:

4/7 as a percent. Round to the nearest tenth of a percent

= 0.57142 = 57.142% = 57.1% C

.709 as a percent

70.9% B

81.25% of 21 = about 16 A

48% of 23.95 = about 12.00 A

15% of $58.50 = about 5.8 + 2.9 = 8.7 = about 9 B

50 is 12.5?

12.5/50 = 25/100 = 25% B

50 is 6.25% of what number

50 = 0.625 times X

So x = 50/0.625 = 80 B

50% of 70% = 35

So the proportion would x/70 = 50/100 A
