Assuming by "1 over 3", you mean a fraction with 1 in the numerator and 3 in the denominator (1/3), it equals 0.3333333333333333... (0 with an infinite amount of 3's after the decimal).
The numerator is 1 and the denominator is 7.
2 over 3 cannot be a mixed number because the numerator is smaller than the denominator
The relationship between 1 over 4 and 3 over 4 is that they both share the same denominator, which is 4.

(1 over radical three) over three - I assume that's how you are describing it - can be simplified like any division problem involving fractions in the numerator and denominator. To solve the problem, you take the fraction in the denominator (in this case 3 over 1) and invert it (making it 1 over 3) and multiply it by the numerator. You would have (1 over radical 3) times (1 over 3) which would give you 1 over (3 times radical 3)
