## Calculating the Answer as a Number

The simple rule to remember whenever you want to find a fraction of an amount is to divide the amount by the fraction's denominator, and then multiply that answer by the fraction. Using this rule, you'll be able to work out the fractional amount of the original number. Let's work it out together.

First we take the amount, 458, and divide it by the denominator, 1:

Next, we take the answer, 458, and multiply it by the numerator, 1:

As you can see, the answer to the question "what is 1/1 of 458?" as a number is 458.

## Increase or Decrease an Amount by a Fraction

What if you wanted to increase or decrease 458 by 1/1? Once you have calculated the answer above, 458, you deduct that amount from the whole number to decrease it by 1/1 and you add it to increase:

Increase = 458 + 458 = 916

Decrease = 458 - 458 = 0

## Calculating the Answer as a Fraction

Sometimes, you might want to show your answer as another fraction. In that case, we can do the following.

First, we take the whole number and turn it into a fraction by using 1 as the fraction denominator:

Now that we have two fractions, we can multiply the numerators and denominators together to get our answer in fraction form:

Now you might have noticed that the fraction we have has a numerator that is larger than the denominator. This is called a mixed or improper fraction and means that there is a whole number involved. We can simplify this down to a mixed number.

We'll put together a blog post on converting improper fractions to a mixed number to explain those steps in more detail, but for the purposes of this article, we'll go ahead and just give you the mixed number answer:

458

Hopefully this article helps you to understand how you can work with fractions of whole numbers and work this out quickly for yourself whenever you need it.
