#### When you are looking for differences in fractions, you primary goal is make sure that both of them have a common denominator. If the denominators are already the same, you just have to subtract the larger numerator by the smaller numerator. A quick trick to use, if the denominators differs is to multiply each part of the fraction (top and bottom) by one of the opposite denominators. If you do this, you will surely need to simply your final answer.

How do you subtract like and unlike fractions?
These are values that represents a part of the whole. There are two types of them proper and improper. Proper fractions are those where the denominator is larger than the numerator, and their value in decimals is between 0 and 1. Improper fractions are those where the value of denominator is less than the value of numerator, and the value of these values when found in decimals is greater than 1.
These are subdivided into two types of fractions; those with the same denominators, that we know as like-fractions, and those with different denominators, that we know as unlike-fractions.
While subtracting likes is pretty simple and straightforward, you have to bring the concept of LCM, Least Common Factor into consideration when summing two unlikes. You have to make the denominators the same if you want to sum these fractions.
These worksheets explain how to subtract fractions with both like and unlike denominators. Your students will use these worksheets to learn how to make use of the lowest common denominator with ease.
