Number of pears that Sean used
=
56 x 96
= 80
Number of pears that Sean had left
= 96 - 80
= 16
Number of pomegranates that Sean used
=
34 x 84
= 63
Number of pomegranates that Sean had left
= 84 - 63
= 21
Fraction of the fruits left that were pomegranates
= 1 -
19=
89 Number of pears left = 1 u = 16
Number of pomegranates left in the end
= 8 u
= 8 x 16
= 128
Number of pomegranates that Sean bought
= 128 - 21
= 107
Answer(s): 107
