Question

The product of rational number -2/5 and its multiplicative inverse is

Answer 1

Answer:

If the product of two numbers is 1, then each number is known as multiplicative inverse or the reciprocal of one another. ... Hence, the product of a fractional number and its multiplicative inverse is 1.

Answer 2

Answer:

Any number can be multiplied by its multiplicative inverse, which is always 1, to get any number.

step-by-step explanation:

1/N or N-1 is used to denote a number's multiplicative inverse, such as the number N. From the Latin word "reciprocus," it is also known as reciprocated. Inverse refers to something that is the reverse. The acquired opposite of a number is such that its value equals identity 1 when multiplied by the original number. In other terms, it is a technique for producing identity 1 by diluting a number by itself, as in N/N = 1.

For any n, the multiplicative inverse of a number is just 1/n.

1 / x  or  x-1 (Inverse of x)

The multiplicative identity of a number is 1 and the reciprocal of a number is t.

product of rational number $-\frac{2}{5}$ and its

multiplicative inverse is $-\frac{2}{5} *-\frac{2}{5}$

                                      $=1$
