(a)
Fraction of the persimmons left
= 1 -
14 =
34 Fraction of the mangoes left
= 1 -
57 =
27The number of persimmons and mangoes left were the same. Make the number of persimmons and mangoes left the same. LCM of 3 and 2 is 6.
Number of persimmons at first = 8 u
Number of mangoes at first = 7 u
8 u = 72
1 u = 72 ÷ 8 = 9
Number of persimmons left
= 2 u
= 2 x 9
= 18
(b)
Number of mangoes at first
= 7 u
= 7 x 9
= 63
Answer(s): (a) 18; (b) 63
