Things You Should Know About Calculating Fractions Mathematicians are those people that knows a lot about fractions and knows how to compute them. In this article, you will read about fractions and how to calculate them. Below are important factors that you should know about fractions: A fraction consist of 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.
Getting Down To Basics with Calculators
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.
Finding Similarities Between Tips and Life
Multiplying fractions is an easy process. When multiplying fractions it should 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 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. 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 use any kind of common denominator, however it will be easier for you to solve the problem if you find the smallest common denominator. If you cannot find 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. You need to change the mixed number first. The computation of a fraction and a mixed number is not an easy task to do. You need to change the mixed number to 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. However, you can also change it into a mixed number and you can do this by dividing it. 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 also help you determine if the fractions are the same. You will also need to cancel the number that is divided by one. This also you to easily solve the problem.
