The quickest and easiest definition for a fraction is that it represents the part of a whole (whole). For this reason, although it does not attract much attention, it can be used with a lot of emphasis in people's daily lives.

It is a numerical representation of the quantity, being possible to carry out operations such as addition, subtraction, multiplication and division.

The fraction can be represented in several ways: on a number line (1/2), which means that half of an integer has been removed. That is, the number represented by 1/2 is between zero (0) and one (1). It also takes the form of a percentage, numbers decimals (numbers with a comma) and mixed numbers.

## Day-to-day representations

To see how many fractions there are in people's lives, pay attention to a few examples:

### Pizza with friends

A simple trip to the pizzeria with friends can represent a real math class, where the topic is fractions. Doubt? So pay attention! You have a great pizza from the waiter.

When it reaches the table it is divided into eight slices. That is, each of the parts is called 1/8 (one eighth). If you eat three slices of pizza, it means you ate 3/8 (three-eighths).

### Kitchen Recipes

Another way to find the use of fractions is through culinary recipes. For example, if 1/2 cup of sugar appears in the ingredient list, that means you should add half a cup.

As for the percentage, it is also a form of fraction. If the same recipe asks you to add 3/4 of a tablespoon of flour, that's 75% of the total.

### Counting money

The monetary system is another way to use the mathematical fraction. If you consider the amount of R \$ 10, for example, as a representation of a whole, R \$ 1 will be one-tenth of the value. In other words, (R \$ 1) corresponds to a fraction of a whole (R \$ 10).
