Title: Dividing rational numbers

For part three of: https://trello.com/c/EqP0nOuH/164-four-operations-with-rational-numbers

Fractions: f1 / f2 or f1 / (f2 / f3) or (f1 / f2) / f3
Terminating decimals: one 2-digit integer or decimal divided by another, or (a / b) / c or a / (b / c). With two numbers can be quite trivial.
Percentages: Same as above, but with percentages - seems a bit weird
Repeating decimals: One repeating decimal over another. I didn't add questions with three numbers as I thought the calculations would become too complex.
