To get the reciprocal of a fraction, just turn it upside down. Like this: 34 NumeratorDenominator We call the top number the Numerator, it is the number of parts we have.Fractions
A Fraction (such as
We call the bottom number the Denominator, it is the number of parts the whole is divided into.
To get the reciprocal of a fraction, just turn it upside down.
In other words swap over the Numerator and Denominator.
Examples:
38 | 8 3 |
56 | 6 5 |
197 | 7 19 |
12 | 21 = 2 |
That last example was interesting. The reciprocal of 12 is 2
Likewise the reciprocal of 13 is 3 and so on.
Multiplying a Fraction by its Reciprocal
When we multiply a fraction by its reciprocal we get 1:
Reciprocal of a Mixed Fraction
To find the reciprocal of a Mixed Fraction, we first convert it to an Improper Fraction, then turn that upside down.
1. Convert it to an improper fraction: 213 = 6 3 + 1 3 = 7 3
2. Turn it upside down: 37
The Answer is: 37
