- How many mangosteens did Liam have at first?

(a)
Fraction of the pears left
= 1 -
15 =
45 Fraction of the mangosteens left
= 1 -
35 =
25The number of pears and mangosteens left were the same. Make the number of pears and mangosteens left the same. LCM of 4 and 2 is 4.
Number of pears at first = 5 u
Number of mangosteens at first = 5 u
5 u = 85
1 u = 85 ÷ 5 = 17
Number of pears left
= 2 u
= 2 x 17
= 34
(b)
Number of mangosteens at first
= 5 u
= 5 x 17
= 85
Answer(s): (a) 34; (b) 85
