2 u |
(a)
Fraction of the lemons left
= 1 -
12 =
12 Fraction of the grapefruits left
= 1 -
35 =
25The number of lemons and grapefruits left were the same. Make the number of lemons and grapefruits left the same. LCM of 1 and 2 is 2.
Number of lemons at first = 4 u
Number of grapefruits at first = 5 u
4 u = 60
1 u = 60 ÷ 4 = 15
Number of lemons left
= 2 u
= 2 x 15
= 30
(b)
Number of grapefruits at first
= 5 u
= 5 x 15
= 75
Answer(s): (a) 30; (b) 75
