It's important to learn about the history of fractions
Let's review it...

A fraction is composed of two parts or two numbers ( a number on top and a number on the bottom): numerator which is the number on top of the fraction, and denominator which is the number on the bottom of the fraction.

We have 3 types of fractions:
* Proper fractions
* Improper fractions
* Mixed fractions

# data[].attributes.body
*When the numerator is smaller than the denominator.

# data[].attributes.body
*When the numerator is bigger or equal to the denominator.

# data[].attributes.body
*A fraction composed by a whole number and a fraction

Even though equivalent fractions may look different, they are fractions that represent the same amount or quantity.
For example:

# data[].attributes.body
Any number that can be written as a fraction in the form a/b
which includes, proper, improper fractions, integers and whole numbers.
For example:

We have a few of simple steps to add fractions:
1. Make sure the denominators of two or more fractions are the same
2. Add the numerators
3. Simplify the fraction if needed and if it is possible.
Example:

8/9 + 6/3= 26/9
As we can see we cannot simplify this fraction:

* When we subtract fractions we do the same thing as in addition, make sure we have the same denominators.
* Subtract the numerators
*Simplify if possible.

14/2- 4/8

When multiplying fractions there are 3 simple steps to follow:
1. Multiply the numerator (top number)
2. Multiply the denominators (bottom numbers)
3. Simplify the fraction if possible.
Example:

Dividing fractions can be easier than you think, here are the steps:
1. Turn the second fraction (upside down just as w do it with reciprocals)
For example if we have 2/3 then it will be 3/2
2. Multiply the first fraction by the reciprocal.
3. Simplify the fraction

After this lesson students should be able to add, subtract, multiply, and divide fractions.
This lesson will help students to understand fractions and help them use fractions in a future or daily lives!
