Reciprocal of a Fraction Calculator is a free online tool that displays the reciprocal or multiplicative inverse of a given number. In general the reciprocal of a fraction simply interchanges the numerator and denominator of the fraction. To find the absolute value, leave the positive numbers the same, but take the opposite of the negative numbers.
What is a reciprocal of 25?
The reciprocal of any number is the quotient you get when you divide 1 by that number. Thus, the reciprocal of 25 is 1 divided by 25 which is: 0.04.
To find the reciprocal of a Mixed Fraction, we first convert it to an Improper Fraction, then turn that upside down. We call the bottom number the Denominator, it is the number of parts the whole is divided into.
Finding the Reciprocal of a Number
The reciprocal of a proper fraction can be easily obtained by switching its numerator and denominator. The second type of opposite number has to do with multiplication and division. It’s called the multiplicative inverse, but it’s more commonly called a reciprocal. This article was co-authored by David Jia.

- Reciprocals are helpful in all sorts of algebraic equations.
- For example, .5 is equal to ½, which would give you a reciprocal of 2/1.
- In general, the first step to finding the reciprocal…
- Then, invert the fraction to find the reciprocal.
- For instance, 2 ½ is the same as 5/2, and the reciprocal is 2/5.

Reciprocals are helpful in all sorts of algebraic equations. For example when you are dividing one fraction by another you multiply the first by the Reciprocal of the 2nd. You might also need reciprocals when finding equations of lines. To find https://business-accounting.net/ the reciprocal of a fraction, switch the numerator and the denominator . So, simply speaking, the reciprocal of a/b is b/a. To find the reciprocal of a number, divide 1 by the number. Q2) Find the reciprocal of each of the following fractions.
of a Fraction
You just pretty much change the number to a fraction, the number is the denominator and is the numerator. In fact, any number you can come up with has an additive inverse.
- Notice that the reciprocal of a number that’s already a fraction is just a flipped fraction.
- Change the division problem to use whole numbers.
- The second type of opposite number has to do with multiplication and division.
- To find the reciprocal of 1/4, invert the numerator and denominator.
- There are two steps to finding the reciprocal of a mixed number, explained below.
- This means that the product of a number x and its reciprocal yields 1.
No matter how large or small a number is, adding it and its inverse will equal 0 every time. Find the reciprocal of a fraction by flipping it. The definition of “reciprocal” is simple. A reciprocal calculator is an online tool that shows the reciprocal of a number or a fraction. Our reciprocal calculator helps you to find the reciprocal of a fraction within a few seconds. Use our calculator to get the reciprocal of 7/8.
What is the reciprocal of 4 3 as a fraction?
To get the reciprocal of a fraction you just need to turn it upside down or swap numerator to denominator i.e. 21 /24 is a fraction which has a value that’s equal to 7/ 8. The reciprocal of \frac is \frac , which is \frac flipped so that the numerator becomes the denominator and vice versa. The reciprocal is also known as the multiplicative inverse. If A is in the form of a fraction, we can think of the reciprocal as the “upside-down” version of the fraction.
We did round the answer above to 8 digits after the decimal point if necessary. As you can expect, 7 times the reciprocal of 7 will equal 1. Also, 1 divided by a negative number will be a negative number. Therefore, the reciprocal of -7 is simply the answer above with a minus in front. To find the reciprocal of any number, just calculate “1 ÷ .”.

The calculator helps in finding value from multiple fractions operations. Solve problems with two, three, or more fractions and numbers in one expression. If you’ve ever multiplied and divided fractions, the reciprocal might seem familiar to you.
To get the reciprocal of 8/7 based on that definition, we can make the following equation where “R” is the reciprocal of 8/7. Here we will define reciprocal of 8/7, and show you how to calculate the reciprocal of 8/7 in fraction form and decimal form. In mathematics, the reciprocal, also known as multiplicative inverse, is the inverse of a number x. This means that the product of a number x and its reciprocal yields 1. To get a positive result when multiplying two numbers, the numbers must have the same sign. To find the reciprocal of a fraction, we invert the fraction.
Reciprocals Of Fractions
The reciprocal of a fraction is just switching the numerator and the denominator . The negative reciprocal takes the negative of that number. Solve each of the following problems, and then check your answers using the key below. Don’t forget to use a reciprocal for the division problems.
Give the number a denominator of 1, then invert it. For instance, to find the reciprocal of 2, turn it into the improper fraction 2/1, then invert it to get ½. If you’re dealing with a mixed number, things get a little trickier. First, change the mixed number into an improper fraction. To do this, multiply the whole number by the denominator of the fraction, then add the product to the numerator.
In this example, the variable is multiplied by 4/5. So each side of the equation needs to be multiplied by the reciprocal 5/4. In other words, a reciprocal takes a number a/b and turns it into b/a. To find the reciprocal of a fraction, you just need to flip the numerator and denominator. The reciprocal of 8/7 is a fraction or a number that when multiplied by 8/7 is equal to 1.
Convert a mixed fraction into an improper fraction as calculated below. To find the reciprocal of a decimal number, change it to a fraction, then flip the fraction.
To find the reciprocal, keep the sign the same and invert the fraction. The additive inverse of a positive number is always negative whereas the additive inverse of a negative number is always positive. In the following video we will show more examples of how to find the reciprocal what is the reciprocal of 7 8 of integers, fractions and mixed numbers. To find the reciprocals, we keep the sign and invert the fractions. The reciprocal of a fraction is its multiplicative inverse. The product of a number and its multiplicative inverse equals 1 . The multiplicative inverse of 119 is 911 .
- Use our calculator to get the reciprocal of 7/8.
- You might also need reciprocals when finding equations of lines.
- Similarly, the reciprocal of a fraction is just that fraction reversed.
- To find the reciprocal of a fraction, flip the numerator and denominator.
- To find the reciprocal of a mixed number, change it into an improper fraction and then invert it.
