Number of pears that Jenson used
=
411 x 66
= 24
Number of pears that Jenson had left
= 66 - 24
= 42
Number of oranges that Jenson used
=
710 x 140
= 98
Number of oranges that Jenson had left
= 140 - 98
= 42
Fraction of the fruits left that were oranges
= 1 -
14=
34 Number of pears left = 1 u = 42
Number of oranges left in the end
= 3 u
= 3 x 42
= 126
Number of oranges that Jenson bought
= 126 - 42
= 84
Answer(s): 84
