Reciprocals of Fractions Worksheets
What Are the Reciprocals of Fractions? A fraction has two parts or components or features. One is the numerator, which is its top part, the other is the denominator, which is its second part. Take the example of this fraction. 2/5. The top part is the numerator, and the bottom part is the denominator. To get the reciprocal of a fraction, all you have to do is turn it upside down, and you will have the reciprocal of a fraction. Invert the above fraction; you will have: 5/2. Examples include: 3/4 = 4/3, 18/9 = 9/18, 1/10 = 10/1. Take a look at the above examples carefully and note that the reciprocal of the fraction 1/10. An interesting thing to note in making reciprocals is that if we happen to have one as a denominator, it will render the fraction as a simple integer, and the number will only be considered 10. To find the reciprocal of a mixed number, first, convert it to an improper fraction and then turn it upside down.
