Example Question #12 : Use Proportional Relationships To Solve Multistep Ratio And Percent Problems: Ccss.Math.Content.7.Rp.A.3
is 30% of ; is 42% of .
is what percent of ?
We can choose a specific value for ; the reasoning is independent of this value.
Assume . Then
and
To find out what percent is of , calculate:

is 40% of , which is 60% of . What percent of is ?
This reasoning is independent of the value of , so choose for simplicity's sake.
is 60% of , which is 60. is 40% of this, or
.
To determine what percent is of , calculate:
Example Question #81 : Percentages
is four-fifths of , which is three-fifths of . By what percent must be increased to get ?
This reasoning is independent of the value of , so, for simplicity's sake, we will set .
is three-fifths of , so .
is four-fifths of , so .
To find out by what percent must be increased to yield , we calculate:
Example Question #604 : Arithmetic
20 is % of what number?
Let be the number in question. If 20 is % of , then
Example Question #81 : Percentages
Four students ran for student body president - Anya, Florida, Moesha, and Winston.
According to the rules, a candidate must win more than 50% of the vote in order to claim an outright victory; otherwise, a runoff must be held between the top two vote-getters. It is known that Florida won 67 votes, Moesha won 91 votes, and Winston won 180 votes. It is also known that there will be a runoff. At the very least, what percent of the vote did Anya win? (Nearest whole percent)
Neither Florida nor Moesha won the most votes, so either Winston or Anya did. If there is going to be a runoff, then regardless of the outcome, the total of the votes won by Winston's opponents must at least equal the votes won by Winston. If we let stand for the number of votes Anya won, then
At the very least, Anya must have won 22 votes, which in this scenario would have been equal to:
This makes 6% the best choice.
Example Question #11 : Use Proportional Relationships To Solve Multistep Ratio And Percent Problems: Ccss.Math.Content.7.Rp.A.3
If you get a 25% discount, what percentage of the original price will you have to pay?
The original price will represent 100% of the item price since that represents the whole for the problem.
If you get 25% off, you must take that away from the 100%.
so you will have to pay 75% of the original price.

What is the sale price of a product that costs if the sale is off the original price?
First, find of :
Then, subtract this value from the whole:

First, multiply:
Then subtract that amount from the original price:
Answer: The sale price is .
