(a)
Fraction of the mangoes left
= 1 -
12 =
12 Fraction of the dragonfruits left
= 1 -
35 =
25The number of mangoes and dragonfruits left were the same. Make the number of mangoes and dragonfruits left the same. LCM of 1 and 2 is 2.
Number of mangoes at first = 4 u
Number of dragonfruits at first = 5 u
4 u = 112
1 u = 112 ÷ 4 = 28
Number of mangoes left
= 2 u
= 2 x 28
= 56
(b)
Number of dragonfruits at first
= 5 u
= 5 x 28
= 140
Answer(s): (a) 56; (b) 140
