No picture, nothing to rate here.
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.
