Chapter 9 add and subtract fractions2/15/2024 ![]() ![]() When an equation calls for adding a negative fraction, we can rewrite the equation as subtracting a positive fraction. The resulting fraction can be simplified to lowest terms or written as a mixed number. When all denominators are alike, simply add or subtract the numerators and place the result over the common denominator. ![]() Least Common Denominator (LCD) then rewrite all fractions in the equation as equivalent fractions using the LCD as the denominator. When fractions have unlike denominators the first step is to find equivalent fractions so that all of the denominators are the same. When the Denominators are Unlike or Different If necessary we can simplify the fraction to lowest terms or a mixed number. When fractions have the same denominators we simply add or subtract the numerators as indicated and place the result over the common denominator. How to Add and Subtract Fractions When the Denominators are the Same You can add and subtract 3 fractions, 4 fractions, 5 fractions and up to 9 fractions at a time. Click the Calculate button to solve the equation and show the work. Select the number of fractions in your equation and then input numerators and denominators in the available fields. Below are some examples of subtracting fractions whose denominators are not alike.Add and subtract proper and improper fractions with this calculator and see the work involved in the solution. When you subtract fractions, you must think about whether they have a common denominator, just like with adding fractions. numerator: the top part of a fraction – the numerator in the fraction \frac Subtracting Fractions.factor: something being multiplied – for 3 \cdot 2 = 6, both 3 and 2 are factors of 6.Simplify a fraction to its lowest termsīefore we get started, here is some important terminology that will help you understand the concepts about working with fractions in this section.Use the common denominator to add or subtract fractions. ![]()
