QUESTION: Evaluate \dfrac{12}{7}\div\dfrac{9}{20}.


ANSWER: To divide these fractions, we need to keep the first fraction the same, change the \div to a \times, and flip the second fraction. Doing so, we get


Then, we do the multiplication:


240 and 63 both have 3 as a factor, so we can simplify our fraction to get


80 and 21 have no common factors, so we are done.
