To find the absolute value, leave the positive numbers the same, but take the opposite of the negative numbers. To find the reciprocal, keep the sign the same and invert the fraction. In the following video we will show more examples of how to find the reciprocal of integers, fractions and mixed numbers. The reciprocal is sometimes called the « multiplicative inverse. » Convert the mixed number into an improper fraction, then find the reciprocal as you normally would. In other words, a reciprocal takes a number a/b and turns it into b/a.

The negative reciprocal takes the negative of that number. The reciprocal of a number is also called its multiplicative inverse. Solve each of the following problems, and then check your answers using the https://business-accounting.net/ key below. Don’t forget to use a reciprocal for the division problems. To get a positive result when multiplying two numbers, the numbers must have the same sign. So reciprocals must have the same sign.

## Reciprocal Of A Mixed Fraction

Just swap the denominator and the numerator. Vector Basics – Example 1 In mathematics, a vector (from the Latin « mover ») is a geometric object that has a magnitude and a direction. Vectors can be added to other vectors according to vector algebra, and can be multiplied by a scalar . Vectors Intro In mathematics, a vector (from the Latin word « vehere » meaning « to carry ») is a geometric entity that has magnitude and direction. Vectors can be added to other vectors according to vector algebra. Vectors play an important role in physics, engineering, and mathematics.

## Reciprocals In Math

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. Explore how to multiply fractions by whole numbers. Learn the characteristics and parts of fractions and improper fractions.

The right way to find the reciprocal depends on the kind of number you’re working with. To find the reciprocal of a decimal, divide 1 by the decimal. If you need to find the reciprocal of a mixed number, change the mixed number to an improper fraction and then flip the fraction. To find the reciprocal of a fraction, flip the numerator and denominator. If you’re trying to find the reciprocal of a whole number, just divide 1 by that number and write it as a fraction.
