(a)
Fraction of the lemons left
= 1 -
23 =
13 Fraction of the persimmons left
= 1 -
57 =
27The number of lemons and persimmons left were the same. Make the number of lemons and persimmons left the same. LCM of 1 and 2 is 2.
Number of lemons at first = 6 u
Number of persimmons at first = 7 u
6 u = 72
1 u = 72 ÷ 6 = 12
Number of lemons left
= 2 u
= 2 x 12
= 24
(b)
Number of persimmons at first
= 7 u
= 7 x 12
= 84
Answer(s): (a) 24; (b) 84
