Mathematicians are those people that knows a lot about fractions and knows how to compute them. This article will provide all of the necessary information that you need to know about fractions.

Below are important information about fractions:

A fraction consist of two parts and they are the numerator and denominator. The numerator is the number of parts and the denominator is the total number of parts.The numerator stands for the number of parts and the denominator stands for the total number of parts.

Any number can be a fraction. You can use any whole number over 1 to transform it into a fraction because the total number of parts in any undivided whole is considered as one.

Multiplying fractions is an easy process. Multiply fractions must be straight across. If you need to multiply a mixed number with a fraction then it is really important that you change it into an improper fraction.

Multiplying by any form of one. The number 1 is considered as the multiplicative since the number will be the same even if it is multiplied to any number. There are instances when you need to change the fraction but remain its value.

The denominator should be the same if you will subtract and add equal fractions.

If the fractions are not equal then you will need to multiply the fractions for in order for the denominators to be the same. This process is known as finding the common denominator. You can actually make use any common denominator, but solving the problem will be easier if you search for the smallest common denominator.

If are having difficulties in searching for the least common denominator of the fractions then you can multiply the fraction on their opposite denomination. If the denominators are the same then you can start adding or subtracting the numerators.

Mixed numbers is a combination of a fraction and a whole number. It is important that you transform the mixed number first. Computing a fraction with a mixed number is a bit difficult. Mixed numbers must be changed into an improper fraction. You should make use of addition to transform mixed numbers.

The numerator of an improper fraction is much larger than its denominator. If you want to change it back into a mixed number then you need to use division.

You can easily compare products by making use of cross product. You need to diagonally multiply the fractions first before you can compare the products. Cross product method can also help you determine if the fractions are the same.

You will also need to cancel the number that is divided by one. Canceling makes the process easy to solve.
