What that looks like is this: \(\frac{\frac{3}{4}}{\frac{9}{10}}\). When we divide fractions by fractions, you bring up the lower fraction and flip it upside down to multiply, so it becomes \(\frac{3}{4}*\frac{10}{9}\). If we multiply straight across the top and straight across the bottom we have \(\frac{30}{36}\) which reduces nicely to 5/6. That's your answer.
