How to Add and Subtract Fractions
When the Denominators are the Same
When fractions take the same denominators we simply add or subtract the numerators equally indicated and place the result over the common denominator. If necessary we can simplify the fraction to lowest terms or a mixed number.
When the Denominators are Unlike or Different
When fractions have different denominators the first step is to find equivalent fractions so that all of the denominators are the same. Nosotros find the To the lowest degree Mutual Denominator (LCD) then rewrite all fractions in the equation as equivalent fractions using the LCD as the denominator. When all denominators are alike, just add together or subtract the numerators and place the result over the common denominator. The resulting fraction can exist simplified to lowest terms or written every bit a mixed number.
How to Work With Negative Fractions
When an equation calls for calculation a negative fraction, we can rewrite the equation as subtracting a positive fraction. Likewise, if the equation calls for subtracting a negative fraction, this is the same as calculation a positive fraction and can exist rewritten this manner. This calculator rewrites negative fractions when it shows the work involved in finding the answer.
