## What is a Fraction?

A fraction (from Latin fractus, “broken”) represents a part of a whole or, more generally, any number of equal parts. When spoken in everyday English, a fraction describes how many parts of a certain size there are, for example, one-half, eight-fifths, three-quarters. A common, vulgar, or simple fraction (examples: 1/2 and 2/3) consists of an integer numerator displayed above a line (or before a slash) and an integer denominator displayed below (or after); both numerator and denominator are whole numbers.

## What is 0.4 as a Fraction?

To understand what 0.4 as a fraction is, we need to understand what a fraction is. A fraction is a number that represents a part of a whole. It is usually written as a number followed by a slash, like this: 1/2. This means “one half.” The number before the slash is called the numerator, and the number after the slash is called the denominator. So, in the fraction 1/2, the numerator is 1 and the denominator is 2.

## Decimals and fractions

0.4 as a fraction is 4/10. This is because 0.4 is equal to 4 tenths. When you convert a decimal to a fraction, you simply move the decimal point over to the right side of the number and put it over a power of 10 that corresponds to how many places the decimal point moved. In this case, we moved the decimal point one place to the right, so we put it over 10.

## Percentages

0.4 as a fraction is 40/100. In other words, 0.4 is equal to 40% when converted to a fraction. This is because there are 100 “things” in every percent, and 0.4 of those “things” is 40. To convert a decimal to a fraction, we count the number of decimal places and multiply by 10 (or 100, 1000, etc) for each place. Then, we reduce the fraction (if possible). In this case:

0.4 = 4 × 10-1
= 40 × 10-2
= 40/100

## Converting fractions to decimals

To convert a fraction to a decimal, divide the numerator by the denominator.

In other words, to convert a fraction to a decimal, divide the top number of the fraction by the bottom number of the fraction.

Here is an example:
Convert 0.4 to a fraction
We know that 0.4 = 4/10 (because 4 divided by 10 = 0.4)
