Fractions-What Should Know About It?
Only those people that love math are those that love calculating fractions. In this article, I will be providing important facts about fractions.
Below are important factors that you need to 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.
What Research About Products Can Teach You
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.
The Key Elements of Great Calculators
It is easy to multiply fractions. When multiplying fractions it should 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 because it can be multiplied to any number and the result will still be the same number. There are certain instances when you need to transform the fraction but still remain its value.
When Subtracting and adding equal fractions the denominators should be the same.
However, there are certain instances when the fractions are not equal, if this is the case then you need to multiply it first so that the denominator will be equal. 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 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 should make use of addition to transform mixed numbers.
Improper fraction has a numerator that is much larger than the denominator. You should make use of division if you want to change it back into a mixed number.
The cross product allows you to compare fractions. Before comparing products you will need to diagonally multiply the fractions first. Cross product method can also 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.
