(a)
Fraction of the lemons left
= 1 -
25 =
35 Fraction of the mangosteens left
= 1 -
57 =
27The number of lemons and mangosteens left were the same. Make the number of lemons and mangosteens left the same. LCM of 3 and 2 is 6.
Number of lemons at first = 10 u
Number of mangosteens at first = 7 u
10 u = 60
1 u = 60 ÷ 10 = 6
Number of lemons left
= 2 u
= 2 x 6
= 12
(b)
Number of mangosteens at first
= 7 u
= 7 x 6
= 42
Answer(s): (a) 12; (b) 42
