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.

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

There exists infinite number of rational numbers between 0 & -1.

Yes it can be because a rational number is a number that can be written as a ratio with a fraction with denominator on top and numerator on bottom. You can turn the ratio into decimal or any ways you can and you can find it on a number line...

Irrationals differ from Rationals by definition. If a real number is not a Rational Number then it is Irrational. One way to find out if a number is either Rational or Irrational is to look at its decimal value. If the digits past the decimal point terminate then it is a Rational number. If the digits past the decimal point repeat the same digit forever, of if it repeats a sequence of digits over and over, then it is a Rational Number. If the digits past the decimal point do not repeat in any pattern, and do not stop, then it is an Irrational number. Another way to find out if a number is Rational or Irrational is if it can be exactly described by a fraction (ratio). If it is the same as some fraction, then it is a Rational Number. Irrationals cannot be exactly described as a fraction.

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.

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.

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

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

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.)

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

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.

change it to an improper fraction and then divide it

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

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

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

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