Question

1*2/3,Write additive inverse of the given number.

Answer 1

There is a property of real numbers which says: "For every real number a there exists another real number -a such that a + (-a) = -a + a = 0." Consequently, for real numbers a and -a, each is the additive inverse of the other.

Therefore, the additive inverse of a = 2/3 is -a = -2/3, i.e., negative two-thirds, because:

-2/3 + 2/3 = 2/3 + (-2/3) = 2/3 - 2/3 = 0.

hope it's clear now.
