What is X Percent of Y Calculator** helps you determine the value of R given the values of Y and Percentage X.**

## What is X percent of Y?

- Written as an equation: R = X% * Y
- The ‘what’ is R that we want to solve for
- Remember to first convert percentage to decimal, dividing by 100
- Solution: Solve for Y using the percentage formula

**R = X% * Y**

### How to calculate percentage of a number. Use the percentage formula: X% * Y = R

**Example 1: What is 10% of 150?**

- Convert the problem to an equation using the percentage formula: X% * Y = R
- X is 10%, Y is 150, so the equation is 10% * 150 = R
- Convert 10% to a decimal by removing the percent sign and dividing by 100: 10/100 = 0.10
- Substitute 0.10 for 10% in the equation: 10% * 150 = R becomes 0.10 * 150 = R
- Do the math: 0.10 * 150 = 15
- R = 15
- So 10% of 150 is 15
- Double-check your answer with the original question: What is 10% of 150? Multiply 0.10 * 150 =
**15**

**Example 2: **What is 10% of 25?

- Written using the percentage formula:
**R = 10% * 25** - First convert percentage to a decimal 10/100 = 0.1
- R = 0.1 * 25 = 2.5
- So 10% of 25 is 2.5

### Percentage Tips And Tricks

Now let’s go through the short tricks that you can use to find the Percentage of any number in less time:

**Q1. What is 5% of 1220?**

10% of 1220 is 122.

You know that 5% is half of 10%. So, half of 122 is 61.

**Q2. What is 15% of 400?**

10% of 400 is 40.

As you know that 5% is half of 10%. So, 5% of 400 = 40/2 = 20.

So add 10% of 400 and 5% of 400 = that will give 15% of 400 which is 40 + 20 = 60.

Another method is that you just multiply 15 with 4. Forget about two zeros since they will be canceled by 100.

**Q3. How to calculate 85% of a number?**

Number (15% of Number) = Answer

**Q5. What is 20% of 400?**

Just multiply 2 with 40 = 80. Forget about one zero present in 20 and 400 each, because two zeros will be canceled with 100.

**Q4. What is 3% of 400?**

1% of 400 is 4.

Multiply 1% with 3 to get (3% of 400) = 4 * 3 = 12.
