Simplifying
How can I simplify the following...
$\displaystyle 149/4^2 2^3$
The test puts it exactly in this format I don't understand if it's to confuse me? Or I simply don't know my math very well.
Here I will use PEMDAS.
My solution
$\displaystyle 14\frac{9}{16}8$
$\displaystyle \frac{14}{1}\frac{9}{16}8$
=$\displaystyle \frac{224}{16}\frac{9}{16}8$
=$\displaystyle \frac{215}{16}\frac{128}{16}$
=$\displaystyle \frac{87}{16}$
or
=$\displaystyle 5\frac{7}{16}$

Re: Simplifying
This is correct.
Edit: A simpler way is
$\displaystyle 14\frac{9}{16}8=6\frac{9}{16}=5+\frac{16}{16}\frac{9}{16}=5\frac{7}{16}$

Weird my sample test is not providing me the right answer.
Probably the test did not include the "NONE OF THESE" answer.
