Question

which number is the additive inverse of -10 1/4

Answer 1

Additive inverse of a number is the number that should be added to the number to result in zero.

Eg additive inverse of -2 is +2, because -2 + 2 = 0

Similarly additive inverse of - 10 1/4   is  +10  1/4.  

Answer 2

The additive inverse of the number -10 1/4 is +41/4

The additive inverse of any number is such a number added to the given number to get zero.

Let the additive inverse of the given number be "x", hence:

-10 1/4 + x = 0

x = 0 - (-10 1/4)

x = 10 1/4

x = 41/4

Hence the additive inverse of the number -10 1/4 is +41/4
