Best Answer

You take its reciprocal, that is you divide 1 by the number.

A rational number can be written as a fraction with integer values in both the numerator and denominator, j/k. The multiplicative inverse of a number is what you have to multiply by to get a product of 1. Putting these ideas together, the multiplicative inverse is the reciprocal, or k/j:

(j/k) * (k/j) = 1.

How do you determine the multiplicative inverse of a number?

The multiplicative inverse of a number is its reciprocal, meaning the multiplicative inverse of the rational number a/b is b/a. In the specialized case for integers, the multiplicative inverse of n is 1/n. This is due to the fact that a/b * b/a = 1 and n * 1/n = 1, which is the definition of a multiplicative inverse. More succinctly, to find the multiplicative inverse you "flip" the fraction or integer around to its reciprocal. This is the number that when multiplied with the original number results in a product of 1.


What is the definition of multiplicitive inverse?

The definition of an multipilicative inverse is a number that's times by the known number to attain a product of one. To find the multiplicative inverse is the same thing as the recipricol of the number. To find the multiplicitive inverse or recipricol of a number, first turn the number into a fraction, then switch the numerator and denominator around. The result is your multiplicitive inverse.


How do you find the multiplicative inverse of a whole number?

Divide 1 by the number. The multiplicative inverse of 7 is 1/7, for example.


How do you find the opposite of a number?

The answer depends on what you mean by "opposite": whether it is the additive inverse or the multiplicative inverse.


What is the additive inverse of 5 number?

To find the additive inverse of ANY number, add a minus sign. (If the number already has a minus sign, take the minus sign away to get the additive inverse.)


How do you find the opposite of a decimal number?

The answer depends on what you mean by "opposite": whether it is the additive inverse or the multiplicative inverse.


Find the inverse log of negative 3.1?

The inverse of the logarithm of a number is ten to the number, meaning that the number is the exponent. In this case, 10^-3.1 equals approximately .0007943.


How do you find the inverse of a mixed number?

change it to an improper fraction and then divide it


How do you find a rational number between 2 and 2 and a half?

The average of the two will be rational and it will be between them.


What thought process would you use when trying to find the additive or multiplication inverse of a number or expression?

Additive inverse: change all signs. Multiplicative inverse: flip it over.


How do you find the square root of a rational number?

It is the number that youve hat to square to get to that number.


How can you use division to find the decimal equivalent of a rational number?

Divide the numerator of the rational number by its denominator. The quotient is the decimal equivalent.
