How to Create Reciprocals - Have you ever come across reciprocals? If you haven't, let us tell you that reciprocals are the most interesting part of mathematics. In its true essence, reciprocal of a number is when we divide 1 by the number. For example, the reciprocal of the number 8 is 1/8. If you want to understand reciprocals and know the trick of creating them, let's find out how you can create reciprocals. Follow the instructions to create reciprocals: To create a reciprocal, simply divide 1 by the given number. If the number is not a whole number and is a fraction, you can create its reciprocal by flipping the number. For example, the fraction is 2/3; it's reciprocal would be 3/2. The reciprocal of a variable x/ (x-1) would be x-1/x; it is simply the upside-down of the variable. Another form of reciprocal is called flipping a flip; in this form, you create a reciprocal and get the answer, then create the reciprocal of the answer and get it back in its original form. This is called flipping a flip. Reciprocal in it's simplest form is also notation. The reciprocal of x is 1/x or x - 1. This is the reciprocal as well as notation of x. These worksheets and lessons will help students under what a reciprocal is and how to create them.
