I'm running through the drills on PR and I'm stumped on this one.
I've tried to break into steps as detailed below but do not appear to be getting the right answer. I was wondering if someone could review the steps and identify where I've gone off track.
Question:
((\frac{4}{5} / \frac{3}{5}) * (\frac{1}{8} / \frac{2}{3})) / \frac{3}{4}
Choices:
\frac{3}{100}
\frac{3}{16}
\frac{1}{3} (Correct Answer)
1
\frac{7}{16}
Now for each fraction that is divided I make sure I'm inversing the second figure before multiplying
so \frac{4}{5} * \frac{5}{3} = \frac{20}{15}
and \frac{1}{8} * \frac{3}{2} = \frac{3}{16}
then multiplying the two fractions together \frac{20}{15} * \frac{3}{16} = \frac{10}{16}
Finally \frac{10}{16} / \frac{4}{3} = \frac{5}{6}
