# What is 25% of 90?

##### 1 Answer

25% of 90 is 22.5.

#### Explanation:

A percent is any number over 100, so 25% is 25 over 100, this means that 25% can be written as:

Now, any number in fractional form (a number over a number) is the same as division so 25% can also be written as a decimal, we just move the decimal point 2 places to the right of 25, like this:

Now we have two ways that we can solve this problem! I'll start with the fractional method of solving.

**---------------------------**

**The Fractional Method**

So we have a fraction:

and

so that means,

or

This means that we need four 25's to get 100.

or,

(we could also divide both numerator and denominator by 5 to get the same result:

Now that we know 25% is equal to **divide 90 by 4**, its easiest (for me anyway) to just divide 90 by 4.

**---------------------**

**The Decimal Method**

As we found out above 25% equals 0.25 so we can solve this problem using decimals too! All we need to do is multiply 90 by 0.25, which gives us the same answer as above.

**---------------------**

Despite the fact that that mathematics seemed to be a lot more involved in the fractional method, the calculations were a lot easier and personally I found it to be faster than the decimal method. The decimal method is great when you're working with fractions that aren't equal to 100 (For example:

Sorry this is so long, I hope it helped though!
