Find the percent when the amount and base are known
amount / base = percent
2.16 = amount
4.80 = base
- - - - -
2.16 / 4.80 = 0.45
Multiply 0.45 times 100 and attach the % sign
0.45 x 100 = 45%
2.16 is 45% of 4.80

no matter how they ask the question, you can answer this by turning the words into an equation...
what percentage = y
of = times
is = equal sign
So what percentage of $ 4.80 is $ 2.16?
y% x 4.80 = 2.16
4.8y = 2.16
divide both sides by 4.8
y = ,45
Now the question asks for what percent?
so change .45 into a percent by moving decimal 2 places to the right,
answer is 45%
