    Answer:

    17 pieces

    Step-by-step explanation:

    The student use 1\dfrac{1}{4} yards of paper for one box and \dfrac{7}{8} yard of paper for the other box.

    Total no of rolls required is the sum of  1\dfrac{1}{4} yards and \dfrac{7}{8} yard. So,

    S=1\dfrac{1}{4}+\dfrac{7}{8}\\\\=\dfrac{5}{4}+\dfrac{7}{8}\\\\=\dfrac{17}{8}

    Let there are x no of pieces will the student cut to use for the gift boxes. It can be calculated as :

    x=\dfrac{\dfrac{17}{8}}{\dfrac{1}{8}}\\\\=17

    Hence, the student will cut 17 pieces to use the gift boxes.
