If you want to add fractions, you need to first make them like fractions, this means both fractions need to have the same denominator without changing its proportion:

7/10 = 70/100
17/100 = 17/100

Now it is the same and you can add them now because they are like fractions.

70/100 + 17/100 = 87/100

Your answer is B.
