Number of pears that Flynn used
=
35 x 140
= 84
Number of pears that Flynn had left
= 140 - 84
= 56
Number of kiwis that Flynn used
=
37 x 56
= 24
Number of kiwis that Flynn had left
= 56 - 24
= 32
Fraction of the fruits left that were kiwis
= 1 -
15=
45 Number of pears left = 1 u = 56
Number of kiwis left in the end
= 4 u
= 4 x 56
= 224
Number of kiwis that Flynn bought
= 224 - 32
= 192
Answer(s): 192
