Five and twenty six twenty eighths.

Step-by-step explanation:

Start with writing the fractions in numbers:

The 2 next to the first fraction is considered a whole number therefore we can say:

then,  

The 3 is also considered a whole number therefore:

then,

We got our 2 fractions without whole numbers now which makes it easier to add them up however they have different denominators meaning we can't add them.

not possible to add up.

We have to find a common factor, we will do this by looking at our times tables and realizing that 7x4= 28 and 4*7= 28. This will ensure both dominators are the same.

Now we got both fractions with equal denominators which means we can add them up as you would with normal numbers:

We need to make sure to simplify the resultant fraction now, we know that 28*5= 140 and 28*6= 168, we will use 5 as our whole unit since it fits (168 is greater than 166 therefore we can't use that):

(this is the answer on the answer choices)

Now just simplify 26 over 28:

This gives us our final answer of 5 and thirteen fourteenths however judging from the answer choices our answer will be five and twenty six twenty eighths.
