# Find a rational number exactly halfway between: -1/3 and 1/3

**Solution:**

We know that

A __rational number__ that is halfway between a and b = (a + b)/2

The given rational numbers are -1/3 and 1/3

Consider a = -1/3 and b = 1/3

Substituting the values

Rational number = [-1/3 + 1/3]/2

So we get

Rational number = 0/2 = 0

Therefore, the rational number exactly halfway between is 0.
