4 u |
(a)
Fraction of the pears left
= 1 -
23 =
13 Fraction of the starfruits left
= 1 -
37 =
47The number of pears and starfruits left were the same. Make the number of pears and starfruits left the same. LCM of 1 and 4 is 4.
Number of pears at first = 12 u
Number of starfruits at first = 7 u
12 u = 120
1 u = 120 ÷ 12 = 10
Number of pears left
= 4 u
= 4 x 10
= 40
(b)
Number of starfruits at first
= 7 u
= 7 x 10
= 70
Answer(s): (a) 40; (b) 70
