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.

(If not, you can always check out our lesson on multiplying and dividing fractions.) When you multiply two fractions, you multiply straight across. The numerators get multiplied, and the denominators get multiplied.

Reciprocals – Definition & Examples

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 https://business-accounting.net/ 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.

To find 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. To check this answer, we look to see if \frac times \frac is equal to 1. The reciprocal of a number is simply the number that has been flipped or inverted upside-down. This entails transposing a number such that the numerator and denominator are placed at the bottom and top respectively. The fractions \Large\frac[/latex] and \Large\frac[/latex] are related to each other in a special way.

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.

This is also known as the negative reciprocal. The reciprocal of a fraction is the fraction flipped… The reciprocal for a whole number, for example, #6#.

To find the reciprocal of a mixed number, change it into an improper fraction and then invert it. Change the division problem to use whole numbers. The first step to dividing decimals is to move the decimal point until all the numbers involved are whole numbers. In this case, you’ve moved each decimal place one space to the right, which is the same as multiplying each number by ten. In general, the reciprocal of a fraction simply interchanges the numerator and denominator of the fraction.
