Percentage/Percent Game
Solving percentage problems can seem confusing because there are three different types, but they all follow a single, simple formula: Part = Percent × Whole. The key is to figure out which piece of the puzzle you’re missing and then rearrange the formula to solve for it. Scroll down the page for a more detailed explanation.
 
This game will randomly generate problems from these categories:

1. Finding the percentage of a number (e.g., What is 20% of 50?).
   
2. Finding the whole number (e.g., 10 is 20% of what number?).
   
3. Finding the percentage (e.g., 10 is what percent of 50?).
   It will provide instant feedback to help you master each type.

How to solve percentage problems
To solve percent problems, use the equation
Part = Percent × Whole
 
Type 1: Finding the Part
This is the most common type. You are given a percentage and the whole amount, and you need to find the specific part.
Example: What is 25% of 80?
Part: This is what we’re looking for. Let’s call it x.
Percent: This is 25%, or as a decimal, 0.25. (Always convert the percentage to a decimal by dividing by 100.)
Whole: This is 80.
Now, plug these into the formula:
x = 0.25×80
x = 20
So, 20 is 25% of 80.
 
Type 2: Finding the Whole
In this type of problem, you are given the part and the percentage, and you need to find the total amount (the whole). You’ll have to rearrange the formula.
Example: 15 is 30% of what number?
Part: This is 15.
Percent: This is 30%, or 0.30.
Whole: This is what we’re looking for. Let’s call it x.
Plug these into the formula:
15 = 0.30 × x
To get x by itself, divide both sides by 0.30:
15 ÷ 0.30 = x
50 = x
So, 15 is 30% of 50.
 
Type 3: Finding the Percent
Here, you’re given the part and the whole, and you need to find the percentage. This also requires rearranging the formula.
Example: 12 is what percent of 60?
Part: This is 12.
Percent: This is what we’re looking for. Let’s call it x.
Whole: This is 60.
Plug these into the formula:
12 = x × 60
To get x by itself, divide both sides by 60:
12 ÷ 60 = x
0.2 = x
Remember, this result is a decimal, so you need to convert it back to a percentage by multiplying by 100:
0.2 × 100 = 20%
So, 12 is 20% of 60.
The key is to read the problem carefully to figure out which piece of the formula is missing.
