Number of kiwis that Jeremy used
=
411 x 66
= 24
Number of kiwis that Jeremy had left
= 66 - 24
= 42
Number of chikoos that Jeremy used
=
710 x 170
= 119
Number of chikoos that Jeremy had left
= 170 - 119
= 51
Fraction of the fruits left that were chikoos
= 1 -
18=
78 Number of kiwis left = 1 u = 42
Number of chikoos left in the end
= 7 u
= 7 x 42
= 294
Number of chikoos that Jeremy bought
= 294 - 51
= 243
Answer(s): 243
