**Question**: I’m trying to calculate what percentage is 12 out of 15. How do I do that?

**MathBlog**: A percent tells us how many parts out of 100 something is. To write a percent as a fraction, just remove the percent symbol and write the number over 100 as the denominator. Below we explain what is 12 out of 15 in percentage, and how you calculate it.

## What is 12/15 in percentage?

**Answer**: 12 is 80% out of 15.

We have two methods to figure out what is 12/15 in percent, with steps for easy understanding.

### Method 1: Long division with remainder

Calculate \( 12:15 \)

- 15 enters into 12,
`0 times`

, remainder 12`Result (ongoing) =`

**0.**

Multiply the remainder by 10 to get 120. Now calculate 120 : 15 - 15 enters into 120,
`8 times`

, remainder 0

Remainder = 0, means you're done.`Result (final) =`

**0.8**

Now you multiply the reults by 100 \( (0.8 \times 100 = 80 ) \) and you get 80%.

**Solution**: 12 out of 15 equals 80%.

### Method 2: Using fractions

Calculate \( P(\text{%}) = \frac{ 12 }{ 15 } \times 100 \)

We need to get the fraction to be of the type \( \frac{ P }{ 100 } \times 100 \)

In our case we need \( \frac { 12 \times x }{ 15 \times x } \times 100 \)

That means \( 15 \times x = 100 \)

\( x = \frac{100}{ 15 } = 6.6666666666667 \)

Our fraction is now \( \frac { 12 \times 6.6666666666667 }{ 15 \times 6.6666666666667 } \times 100 \)

We know that the denominator \( 15 \times 6.6666666666667 = 100 \) so we construct the fraction again.

\( P = \frac { 12 \times 6.6666666666667 }{100} \times 100 \)

\(= 12 \times 6.6666666666667 \)Since \( 12 \times 6.6666666666667 = 80 \), we have our result

\( P = 80 \).

**Solution**: 12 out of 15 equals 80%.
