Answer 1

Answer:

A and B

Explanation:

To find the answer in these problems you must first convert the mixed numbers to improper fractions using the equations $a \frac{b}{c} =\frac{a*c+b}{c}$.

So for the top equation you would have to do something like $9\frac{7}{8}=\frac{9*8+7}{8}$ which equals: $\frac{79}{8}$

And make sure to do that for both mixed numbers.

You would then plug those mixed numbers back into the equation like so: $(\frac{79}{8}+\frac{14}{5})-\frac{1}{2}$

Multiply them together to get $\frac{507}{40}$

then subtract that by 1/2

convert it back into a mixed fraction.

and you should get $12\frac{7}{40}$ as your answer.

You then must do that for all the questions and find whichever ones match with that one.
