Number of mangoes that Cole used
=
35 x 115
= 69
Number of mangoes that Cole had left
= 115 - 69
= 46
Number of mangosteens that Cole used
=
56 x 144
= 120
Number of mangosteens that Cole had left
= 144 - 120
= 24
Fraction of the fruits left that were mangosteens
= 1 -
13=
23 Number of mangoes left = 1 u = 46
Number of mangosteens left in the end
= 2 u
= 2 x 46
