(a)
Fraction of the mangoes left
= 1 -
14 =
34 Fraction of the persimmons left
= 1 -
57 =
27The number of mangoes and persimmons left were the same. Make the number of mangoes and persimmons left the same. LCM of 3 and 2 is 6.
Number of mangoes at first = 8 u
Number of persimmons at first = 7 u
8 u = 80
1 u = 80 ÷ 8 = 10
Number of mangoes left
= 2 u
= 2 x 10
= 20
(b)
Number of persimmons at first
= 7 u
= 7 x 10
= 70
Answer(s): (a) 20; (b) 70
