- How many mangosteens did Archie have at first?

(a)
Fraction of the starfruits left
= 1 -
35 =
25 Fraction of the mangosteens left
= 1 -
47 =
37The number of starfruits and mangosteens left were the same. Make the number of starfruits and mangosteens left the same. LCM of 2 and 3 is 6.
Number of starfruits at first = 15 u
Number of mangosteens at first = 7 u
15 u = 105
1 u = 105 ÷ 15 = 7
Number of starfruits left
= 3 u
= 3 x 7
= 21
(b)
Number of mangosteens at first
= 7 u
= 7 x 7
= 49
Answer(s): (a) 21; (b) 49
