Answer:
1/3, 3, -1/3
Explanation:
A rational number is a number that can be expressed with a fraction. In this case we have:
1/3 , 3 (all natural numbers are also rational: in fact for example 3 can be expressed with the fraction: 3/1) , -1/3
333/0 is not a rational number because the division is impossible
√3 is not rational because can’t be expressed with a fraction
