A) The question is "What percent of 60 is 80?".

Percent equation is a = p% • b  where a = 80 and b = 60.

80 = p% • 60

80 / 60 = (p% • 60) / 60 

80 / 60 = p%

1.3333 = p%

Write decimal as a percent.

p% = 133.33%

The answer is "133.33 percent of 60 is 80".

B) The question is "Two is four percent of what #?".

Percent equation is a = p% • b  where a = 2, b = # and p = 4.

2 = 4 % • #

Write percent as a decimal.

2 = 0.04 • #

2 / 0.04 = (0.04 • #) / 0.04

2 / 0.04 = #

50 = #

The answer is "Two is four percent of 50".

C) The question is "What if 16.5% of 80?".

Percent equation is a = p% • b  where b = 80 and p = 16.5.

a = 16.5 % • 80

Write percent as a decimal.

a = 0.165 • 80

a = 13.2

The answer is "13.2 is 16.5% of 80".
