Question

Christina is planning a dance routine. at the end of each measure of music, she will make a 1 1/4 turn. how many turns will she make after the first 3 measures of music

Answer 1

1 $\frac{1}{4}$ is equal to $ \frac{5}{4}$  ( $\frac{4}{4} + \frac{1}{4}$ ). To get your answer all you need to do is multiply the numerator 5, by the number of times Christina goes through the routine. You therefore get the answer:
$\frac{5*3}{4} = \frac{15}{4}$
this simplifies to 3 $\frac{3}{4}$
