Question

What number should be added to 3/7 so that the sum is additive identity

Answer 1

Answer:

additive identity is zero.

3/7 + _____ = 0

______ = 0 -3/7 = -3/7

therefore -3/4 must be added to 3/7 to get additive identity

Answer 2

Answer:

The number should be added to $\frac{3}{7}$  get the additive identity =  - $\frac{3}{7}$

Step-by-step explanation:

We know that $\frac{3}{7}$ is a rational number

The additive identity of the set of rational numbers = 0

To get 0, we should add the  additive inverse of a rational number to the number

The additive inverse of $\frac{3}{7}$ = - $\frac{3}{7}$

∴The number should be added to $\frac{3}{7}$  get the additive identity =  - $\frac{3}{7}$
