Fractions-What Should Know About It?
You will notice, that only mathematicians are those that really love computing fractions. 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.
The Best Advice About Products I’ve Ever Written
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.
The Ultimate Guide to Options
Multiplying fractions is an easy process. When multiplying fractions it must be straight across. If the multiplication problem has mixed numbers then it is important that you change it to 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.
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. When the denominators are similar then you should start subtracting and adding the numerators of the fraction.
Mixed numbers is a combination of a fraction and a whole number. It is important that you transform the mixed number 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 change mixed numbers into an improper fraction through addition.
The numerator of an improper fraction is much larger than its denominator. However, you can also change it into a mixed number and you can do this by dividing it.
You can easily compare products by making use of cross product. Before you compare it you will need to diagonally multiply the fractions first. 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. This also you to easily solve the problem.
