3 The Four Operations with Fractions
When you use the four processes with fractions, they behave like whole numbers and decimal numbers, and there are calculators available to do fraction calculations. This is a worthwhile investment for a baker. If you don’t have access to a kitchen calculator or another calculator that has fraction functions, here is a helpful link you can use to do fraction calculations: Calculator Soup You may use this link for assignments and quizzes in this class.
Addition and subtraction word problems with fractions are done the same way as other word problems. Here are a couple of examples:
If the recipe calls for cup of sugar, and cups of brown sugar, how much sugar will there be in total?
There will be a total of cups of sugar used in the recipe.
If there are 6 cups of rice in the box, and you use cups of rice, how much rice will be left in the box?
There will be cups of rice left in the box.
Many multiplication problems with fractions are done in the same way as other word problems, as well. For example:
If the recipe calls for teaspoons of vanilla, and you want to triple the recipe, how much vanilla will you use?
You will use teaspoons of vanilla.
There is another type of fraction multiplication problem, in which the word “of” is used. For example, if you say, What is of 5? you are really saying, What is The answer would be
Example: If you have a two-quart bottle of oil, and you want to use of it, how much oil would you use?
You will use quarts.
Many division word problems with fractions are done in the same way as other word problems. For example:
If there are cakes, and you want to divide them evenly between two people, how much cake would each person get?
Each person will get cake.
There is another type of fraction division problem, and that is dividing by a fraction. It’s important to understand what it means to divide by a fraction. For example, the problem is really saying, “How many are there in ?” In other words, if you have a half of a cake, how many eighth-sized pieces could you cut from that cake?
There are four in .
THE ORDER OF FRACTIONS IN A DIVISION PROBLEM MAKES A DIFFERENCE! The first fraction in the problem is what you are starting with, and the second fraction is the value of the size or quantity you want to divide what you started with into.
