In this problem, before entering your answer, be sure to reduce your fraction completely. if you get 8/ 6 for your answer, reduce it to 4/3 before entering it, or else it will be marked wrong. also, don't worry if the numerator is larger than the denominator. it is almost always easier and more useful to further calculations to leave such answers as improper fractions rather than to convert them to mixed numbers such as 1and 1/3.

part a

if you have a quarter of a pie and you cut it in half, what fraction of a pie would each slice represent?

give the numerator followed by the denominator, separated by a comma.

part b

find the value of

17/15⋅2/11.

though these numbers aren't quite as nice as the ones from the example or the previous part, the procedure is the same, so this is really no more difficult.

part c

consider the following equivalent expressions:

3/8÷13/12 and 38⋅ab.

what are the values of a and b?
