(a)
Fraction of the starfruits left
= 1 -
14 =
34 Fraction of the mangoes left
= 1 -
35 =
25The number of starfruits and mangoes left were the same. Make the number of starfruits and mangoes left the same. LCM of 3 and 2 is 6.
Number of starfruits at first = 8 u
Number of mangoes at first = 5 u
8 u = 72
1 u = 72 ÷ 8 = 9
Number of starfruits left
= 2 u
= 2 x 9
= 18
(b)
Number of mangoes at first
= 5 u
= 5 x 9
= 45
Answer(s): (a) 18; (b) 45
