For example, 1/8 is actually a bigger value (a bigger slice of pizza) than 1/20. This can be confusing when you are first learning about fractions because we are used to larger numbers corresponding to meaning larger real-world values, but in this case a larger value in the divisor may actually make the value of the entire fraction smaller. This can be a stumbling block… As the denominator gets larger, each fractional part of the whole is actually smaller. If our pizza is sliced into 20 slices, you can imagine that each slice is going to be much smaller. The word denominator is a fancy word that simply means “the thing that divides.” Sometimes instead of denominator you may encounter the word divisor, but it’s the same thing.Īnother way to think about a denominator is to understand it tells you how big each fractional piece is, so for example if our pizza is sliced into eight pieces, you can picture in your mind roughly how big each one is. In our pizza example, the whole is divided into eight parts, so this fraction has a denominator of eight. 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. This page hosts a fraction calculator that can perform addition, subtraction multiplication or division of two fractions.
