Things You Should Know About Calculating Fractions
Only those people that love math are those that love calculating fractions. This article will provide all of the necessary information that you need to know about fractions.
Below are important factors that you should know about fractions:
Fraction has two parts and they are the numerator and denominator. The numerator stands for the number of parts and the denominator stands for the total number of parts.
5 Uses For Tips
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 actually considered as one.

Multiplying fractions is an easy process. When multiplying fractions it 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 known as the multiplicative since it can be multiplied to any number and still be the same number. There are instances when you must change the fraction but should still remain its value.
The denominator should be the same if you will subtract and add equal fractions.
But, there are actually certain cases when the fractions are not equal and if this is the case then you need to multiply it first so that their denominator will be equal. This process is finding the common denominator. You can use any common denominator, however it will be easier if you find the smallest common denominator.
If you are having problems in finding 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. If their are mixed numbers then it would be best if you change it first. The computation of a fraction and a mixed number is not an easy task to do. Mixed numbers must be changed into an improper fraction. You can use addition to transform mixed numbers.
Improper fraction has a numerator that is much larger than the denominator. If you want to change it back into a mixed number then you need to use division.
The cross product allows you to compare fractions. You need to diagonally multiply the fractions first before you can compare the products. Cross product method can really help you determine if the fractions are the same.
You need to cancel the number that is divided by one. It is easier to solve the problem if you can cancel numbers.
