Take 8 1/2 and turn it into 8 4/8 then add it to 5 1/8 to get the total of 13 5/8

Hey there!

Here is your answer:

The proper answer to this question is option " $\frac{109}{8}$ 

Reason:

First write down the equation: 

8 $\frac{1}{2}$ +5 $\frac{1}{8}$ 

Transform the mixed numbers into improper fractions.

8 $\frac{1}{2}$ = $\frac{17}{2}$ 
&
5 $\frac{1}{8}$ = $\frac{41}{8}$ 

Now add:

17×4=68
2×4=8
+
41×1=41
8×1=8
68+41=109

= $\frac{109}{8}$ 

Therefore the answer would be 109/8!

If you need anymore help feel free to ask me!

Hope this helps!
