You've seen them used on tests, phone numbers or anywhere else that number is written. But did you know that most fractions were designed to be written with whole numbers? There are a few cases where fractions were designed to be written with fraction numbers rather than whole numbers, but these are far less common than ordinary ones.

When fractions have unlike denominators the first step is to find equivalent fractions so that all of the denominators are the same. We find the Least Common Denominator (LCD) then rewrite all fractions in the equation as equivalent fractions using the LCD as the denominator. When all denominators are alike, simply add or subtract the numerators and place the result over the common denominator. The resulting fraction can be simplified to lowest terms or written as a mixed number. From the topic above, we already know that there are equivalent fractions-fractions that are the same in value even if they have different numerators and denominators. Simplifying fraction means that using the smallest numerator and denominator but the same value. The fraction is in its simplest form when there is no common factor for numerator and denominator. For example, instead of using 7/14, we can use ½ which is the simplest form.

For fractions which are having same or equal denominators, the sum of fractions is equals to the sum of numerators divided by the common denominators, while for fractions with unlike, unequal or different denominators, the sum of fractions is calculated by using the LCM (least common multiple) method. Users may refer the below solved examples with step by step calculation to learn how to find the equivalent fraction by adding two, three or more fraction numbers with same or unlike denominators.When subtracting fractions, if you take a larger fraction away from a smaller fraction, you will be left with a negative amount. You’ll show the resulting fraction with negative sign on either the whole amount or the numerator. A negative fraction should only have one negative sign. A common mistake is to think you need to put make both the numerator and the denominator negative if you have a negative answer. Don’t do this! If your answer is negative, you should only see one negative sign on the resulting fraction. (Source: www.dadsworksheets.com)
