What percent is 18 out of 30

In a fraction, the number above the line is called the numerator, and the number below the line is called the denominator. The fraction shows how many “pieces” of the number there are, compared to how many there are possible. For instance, in the fraction 18/30, we could say that there are 18 pieces out of a possible 30 pieces.

“Percent” means “per hundred”, so for percentages we want to know how many pieces there are if there are 100 pieces possible. For example, if we look at the percentage 75%, that means we have 75 pieces of the possible 100. Re-writing this in fraction form, we see 75/100.

When converting the fraction into a percent, the first step is to adjust the fraction so that there will be 100 pieces possible (the denominator needs to be changed to 100). To do this, you first divide 100 by the denominator:

10030=3 .333\frac{100}{30} = 3.333

We can then adjust the whole fraction using this number, like so:

18∗3.33330∗3. 333=60100\frac{18*3.333}{30*3.333} = \frac{60}{100}

As you can see, there are 60 pieces out of a possible 100 pieces. Re-writing this as a percentage, we can see that 18/30 as a percentage is 60%.

Solution and how to convert 18 / 30 into a percentage

Fraction to Percent Conversion Summary

We encourage you to check out our introduction to percentage page for a little recap of what percentage is. You can also learn about fractions in our fractions section of the website. Sometimes, you may want to express a fraction in the form of a percentage, or vice-versa. This page will cover the former case. Luckily for us, this problem only requires a bit of multiplication and division. We recommend that you use a calculator, but solving these problems by hand or in your head is possibly too! Here's how we discovered that 18 / 30 = 60% :

• Step 1: Divide 18 by 30 to get the number as a decimal. 18 / 30 = 0.6
• Step 2: Multiply 0.6 by 100. 0.6 times 100 = 60. That's all there is to it!

When are fractions useful?

Fractions are commonly used in everyday life. If you are splitting a bill or trying to score a test, you will often describe the problem using fractions. Sometimes, you may want to express the fraction as a percentage.

Fraction Conversion Table

Find the Denominator

A percentage is a number out of 100, so we need to make our denominator 100!

If the original denominator is 30, we need to solve for how we can make the denominator 100.

To convert this fraction, we would divide 100 by 30, which gives us 3.33.

Find the Numerator

Now, we multiply 3.33 by 18, our original numerator, which is equal to 60

Convert your Fraction to a Percent

Remember, a percentage is any number out of 100. If we can balance 18 / 30 with a new denominator of 100, we can find the percentage of that fraction!

Detailed calculations below

Fractions: brief introduction

A fraction consists of two numbers and the fraction bar:

18/30

The number above the fraction bar is the numerator: 18

The number under the fraction bar is the denominator: 30

To get the fraction's value, divide the numerator by the denominator:

The value = 18 ÷ 30

Percent, p%: short introduction

'Percent (%)' means 'out of one hundred':

p% = p 'out of one hundred',

p% = p/100 = p ÷ 100.

How to convert a fraction to a percentage:

1) Calculate the value of the fraction.

2) Multiply this number by 100.

3) Add the percent sign %

Convert the fraction to a percentage

1. Calculate the value of the fraction:

To get the fraction's value, divide the numerator by the denominator:

18/30 =

18 ÷ 30 =

0.6

A quick note:

100/100 = 100 ÷ 100 = 100% = 1

Multiply a number by the fraction 100/100,
... and its value doesn't change.

n × 100/100 = n × 1 = n, any number n

2. The calculation of the percentage:

0.6 =

0.6 × 100/100 =

(0.6 × 100)/100 =

60/100 =

60%

The answer:

18/30 = 60% Divide the numerator by the denominator + multiply the result by 100 + add the percent sign %

The symbols used: % percent, ÷ division, × multiplication, = the equal sign, / the fraction bar, ≈ approximately the same. Writing numbers: comma ',' - as a thousands separator, point '.' as a decimal mark.

Converting integer or decimal numbers, fractions, proportions and ratios to percentages

It's very simple to write a fraction (a proportion or a ratio) or a decimal number as a percentage.

To convert a fraction:

• - start by dividing the numerator by the denominator
• - then multiply the result by 100%
• By multiplying the result by 100% the value we've got at the previous step is not modified, since 100% = 100/100 = 1
• By multiplying by 100% only the form is being changed - it's written as a percentage.

It's even simpler to write an integer or decimal number as a percentage:

• - simply multiply the number by 100%

Examples

• 1/4 = 0.25 = 0.25 × 100% = (0.25 × 100)% = 25%;
• 7/8 = 0.875 = 0.875 × 100% = (0.875 × 100)% = 87.5%
• 1.3/9.4 ≈ 0.138297 = 0.138297 × 100% = (0.138297 × 100)% = 13.8297%
• 4.3 = 4.3 × 100% = (4.3 × 100)% = 430%;
