Before we get started in the fraction to percentage conversion, let's go over some very quick fraction basics. Remember that a numerator is the number above the fraction line, and the denominator is the number below the fraction line. We'll use this later in the tutorial.

When we are using percentages, what we are really saying is that the percentage is a fraction of 100. "Percent" means per hundred, and so 50% is the same as saying 50/100 or 5/10 in fraction form.

So, since our denominator in 18/30 is 30, we could adjust the fraction to make the denominator 100. To do that, we divide 100 by the denominator:

100 ÷ 30 = 3.3333333333333

Once we have that, we can multiple both the numerator and denominator by this multiple:

18 x 3.3333333333333 / 30 x 3.3333333333333 = 60 / 100

Now we can see that our fraction is 60/100, which means that 18/30 as a percentage is 60%.

We can also work this out in a simpler way by first converting the fraction 18/30 to a decimal. To do that, we simply divide the numerator by the denominator:

18/30 = 0.6

Once we have the answer to that division, we can multiply the answer by 100 to make it a percentage:

0.6 x 100 = 60%

And there you have it! Two different ways to convert 18/30 to a percentage. Both are pretty straightforward and easy to do, but I personally prefer the convert to decimal method as it takes less steps.

I've seen a lot of students get confused whenever a question comes up about converting a fraction to a percentage, but if you follow the steps laid out here it should be simple. That said, you may still need a calculator for more complicated fractions (and you can always use our calculator in the form below).

If you want to practice, grab yourself a pen, a pad, and a calculator and try to convert a few fractions to a percentage yourself.

Hopefully this tutorial has helped you to understand how to convert a fraction to a percentage. You can now go forth and convert fractions to percentages as much as your little heart desires!

  • What is 18/31 as a percentage?

Converting a fraction like 18/30 to its percentage format is a very simple and useful math skill that will help students to understand fractions and how to express them in different ways. In this article, we'll show you exactly how to convert fractions to a percentage and give you lots of examples to help you.

There are two main ways to express a fraction as a percentage:

  1. Divide 100 by the numerator, and then multiply both numerator and denominator by the answer.
  2. Convert the fraction to a decimal first, then multiply the answer by 100.

The first step is to make sure we understand all of the terms in the problem we are trying to solve:

  • Numerator - this is the number above the fraction line. For 1830, the numerator is 18.
  • Denominator - this is the number below the fraction line. For 1830, the denominator is 30.
  • Per cent - "per cent" means parts per hundred, so saying 50%, for example, is the same as the fraction 50100 or 510.

Convert 18/30 to Percentage by Changing Denominator

The first method we have is to convert the fraction so that the denominator is 100. Since "per cent" means parts per hundred, if we can convert the fraction to have 100 as the denominator, we then know that the top number, the numerator, is the percentage.

First, we divide 100 by the denominator:

100 ÷ 30 = 3.3333333333333

Once we have the answer of 3.3333333333333, we can multiply both the numerator and the denominator by it to get our new "percent" fraction:

18 × 3.3333333333333 30 × 3.3333333333333 = 60 100

Our percent fraction is 60/100, which means that 1830 as a percentage is 60%.

Convert 18/30 to Percentage by Converting to Decimal

With this method, we first need to divide the numerator by the denominator:

18 ÷ 30 = 0.6

Once we have the fraction in a decimal format, the answer is then multiplied by 100 to get the correct percentage:

0.6 × 100 = 60%

We can see that this gives us the exact same answer as the first method: 18/30 as a percentage is 60%.

Both methods of converting a fraction to a percentage are pretty straightward and can be applied to any fraction easily when you have learned and memorized the steps involved.

Note, the final percentage is rounded to 2 decimal places to make the answer simple to read and understand.
