Question

Separate positive and negative rational numbers from the following: 

`(-3)/5 , 3/-5 , (-3)/(-5), 3/5 , 0 , (-13)/-3 , 15/-8 , (- 15)/8`

Answer 1

Positive rational numbers are `(-3)/-5 = 3/5`  

`(-13)/-3 = 13/3`

Positive rational numbers: `3/5, 13/3`

Negative rational numbers are `(-3)/5 , 3/-5 , 15/-8 ` and `(- 15)/8` 

Negative rational numbers: `-3/5, -15/8`

0 is neither positive nor negative integer.
