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. To get the reciprocal of a fraction, just turn it upside down. Examples:
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 ReciprocalWhen we multiply a fraction by its reciprocal we get 1: Reciprocal of a Mixed FractionTo 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 The Answer is: 37 Copyright © 2020 MathsIsFun.com Reciprocal is the inverse. In other words when a number and its reciprocal are multiplied together, the product is 1.
If you're wondering how to find the reciprocal, we're here to help with this easy-to-use reciprocal calculator. As you're interested in reciprocals, we suspect that fraction calculators may also be interesting to you. So why not check out our other tools!
A reciprocal in math is one divided by the number in question (also known as the multiplicative inverse). The reciprocal of x = 1/x Alternatively, you can say that if you multiply a number by its reciprocal, you'll get 1: For example, if our chosen number is 5, its reciprocal is 1/5. The multiplication of these two numbers will give us 1: The name reciprocal comes from Latin, possibly from the phrase reque proque, meaning back and forth. The reciprocal number to x may be denoted simply as 1/x but also as x-1. Thus, raising the number to the power of minus one is the same as finding its reciprocal.
So, in short, how to find the reciprocal of a number?
Additionally, our reciprocal calculator will show you the fraction in its simplified form. Remember that 0 doesn't have the reciprocal, as 1/0 is undefined.
We hope that, after our explanation, you now understand the concept of a reciprocal. In that case, let's look at two examples to check how this calculator works! Example 1: What is the reciprocal of 4?
Example 2: What is the reciprocal of 1/2?
0.2. Since we can write 5 as 5/1, if we take the reciprocal, it becomes 1/5, which is 0.2 in decimal form.
3/2 or 1.5. Taking the reciprocal of a fraction means swapping the numerator and the denominator around.
1. Since 1 in fractional form is written as 1/1, taking the reciprocal (swapping around the numerator and the dominator) results in the same thing, 1/1, which is 1.
You find the inverse of a fraction by exchanging the numerator (top number) with the denominator (bottom number) – taking the reciprocal of the fraction. For example, the inversion of the fraction 5/4 is 4/5. |
