Question

If the multiplicative inverse of − 2/5 is added to the multiplicative identity, what is the sum obtained​

Answer 1

Answer:

The additive inverse of a number a is the number that, when added to a, yields zero.

Additive inverse of −7=7

The multiplicative inverse of a number for any n is simply n1.

The reciprocal of a number obtained is such that when it is multiplied with the original number the value equals to identity 1.

Multiplicative inverse of −7=−71

Therefore, required sum is 7−71=48/7

Answer 2

Answer:

Multiplicative inverse of -3/5 =-5/3

The sum of (-3/5)+(-5/3) = -34/15
