# How Fraction is Useful in Real World Applications? A fraction is a helpful mathematical tool for representing a portion of a whole or group of items. Simply put, a fraction contains two parts: the upper part is known as the numerator, and the lower part is known as the denominator. When we divide a whole into small pieces, it becomes a fraction. Fraction is an important concept of mathematics, which can be found by using a fraction calculator by calculator online. Fractions are used in expressing decimals, which means we can represent a decimal in fraction form and vice versa. Fractions are more useful and easy to solve than dealing with decimal representation.

## History of Fraction

Fraction is not a new thing; many ancient civilizations including the Harrapanian, Greeks, Romans, and Egyptians used a number system called a fraction. Fractions were initially adopted by the Chinese towards the end of the fourth century BCE. Then it spread to the Middle East around the 10th century, and finally to Europe in the 16th century. A Scottish mathematician John Napier introduced the fraction in decimal form in 1616. He did the addition of decimal points.

## Notation of Fractions

Fractions have two parts: numerator and denominator. The upper part is called the numerator and the lower one is called the denominator. It tells how many parts of a whole or collection are taken. It shows the total number of equal parts the whole is divided or the total number of the same objects in a collection. For example, 5/7, 5/11, 8/9 Here 5, 5, 8 are the numerator and 7,11,9 are the denominators respectively. When you deal with

For complex fractions addition or subtraction, you can use a fraction calculator, which is an online tool to find fractions addition or subtraction in a few clicks.

## Fraction uses in Everyday Life

In real-life circumstances where precise measurements are necessary, fractions come in useful. They are widely used in fields such as science, engineering, commerce, and finance.

Here are a few examples of using fractions in real life:

1. ### Exchange of Money

In exchanging currencies, we use fractions. For example, in Pakistan, the currency used is rupees and in other countries like America use dollars and 1 dollar is approximately 292 Rs. To estimate how many dollars in rupees we will use fractions. You can use a fraction calculator to find a fraction of a number or apply an arithmetic function to the fraction.

1. ### Recipe Making

In the case of making a recipe we use fractions for example if you bake a cake it contains a specific amount of sugar, flour, eggs, and butter. Let us say for 1 pound of cake if we need to make the same cake for 2 pounds we will increase the ingredient accordingly. Some recipes also specify how many people to serve. If we are creating the same food for multiple persons, we will utilize fractions to change the components accordingly.

1. ### Scientific Calculations

Using fractions in everyday life here is another example of scientific calculations. The exact thing required is accuracy in science, which can be achieved using fractions. A small change in quantity leads to a large change in results. We often ignore decimal values after a point but in the scientific calculation, we consider them for accurate results.

You can use a fraction calculator to find addition or subtraction or multiplication or division of two or more fractions.

1. ### Sports

Fractions are used in showing the result of a sport. In athletics, the distance jumped or thrown is noted in decimal or fraction form for exact measurement. The time taken to complete the race is also counted to seconds for accurate performance analysis of a player or team.

Here are a few examples of using fractions. There is a wide scope when it comes to research and development of new drugs and vaccines because, in the field of medicine, accurate measurement is required. They are heavily used where accurate measurement is required.
