This is how many parts the whole is divided into. The number on the bottom is called the denominator. There are special terms for the numbers that make up a fraction. We represent this as a fraction as 3/8 and we say, “three eighths” when we read it aloud. So in our pizza example, if the whole pizza is cut into eight equal slices, and you eat three slices, you would have eaten three out of the eight parts of the whole. Don’t worry! We’ll make it easy! Real-World Uses for the Fraction CalculatorĪ fraction is a way to represent in mathematical terms a smaller part of a whole of something. We deal with partial amounts every day, so these ideas are familiar even if the way we have to work with them in math at first seems a little intimidating. All of these represent a portion of a whole, and that’s exactly what a fraction is. A half cup of sugar in a recipe or six tenths of amile or a quarter dollar. But the world is full of partial amounts of things. When we learn the basic math operations, we start by dealing with the operations on integers. This fraction calculator is a useful tool, but it’s not a substitute for a powerful mathematical mind! There is no substitute for developing a solid set of concepts, and this lesson provides an interesting introduction to fractions if you are looking for another approach. It will return to the fraction calculator and show the problem exactly as you see it.ĭon’t just use this fraction calculator to race through your homework! Solve the problems on your own, and use the calculator to check your work or see how to work a problem you don’t understand. If you wish to save the fraction calculator showing the problem you're working on, the “Share this Calculation” link can be copied and pasted into an email, your browser bookmarks or a web page. A visualization of the operand fractions and the answer fraction is shown in the panel underneath where the values are entered.Ĭomplete steps for solving each type of fraction operation will be listed in a version of the fraction calculator coming soon! This part of the fraction calculator is designed to illustrate not just the answers, but provide a learning tool so you can see how the problems were solved. Enter the values directly into the corresponding locations in the fraction calculator and the answer will be updated in real time. The values for the calculation can be simple or mixed fractions, or consist of only wholes. Whether you are working with fractions, whole numbers or decimals, use these guidelines when adding and subtracting positive and negative numbers.This page hosts a fraction calculator that can perform addition, subtraction multiplication or division of two fractions. Simplifying Operations on Negative Numbers This calculator rewrites negative fractions when it shows the work involved in finding the answer. Likewise, if the equation calls for subtracting a negative fraction, this is the same as adding a positive fraction and can be rewritten this way. 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. Add and subtract proper and improper fractions with this calculator and see the work involved in the solution.
