(a)
Fraction of the kiwis left
= 1 -
45 =
15 Fraction of the dragonfruits left
= 1 -
57 =
27The number of kiwis and dragonfruits left were the same. Make the number of kiwis and dragonfruits left the same. LCM of 1 and 2 is 2.
Number of kiwis at first = 10 u
Number of dragonfruits at first = 7 u
10 u = 60
1 u = 60 ÷ 10 = 6
Number of kiwis left
= 2 u
= 2 x 6
= 12
(b)
Number of dragonfruits at first
= 7 u
= 7 x 6
= 42
Answer(s): (a) 12; (b) 42
