Fabian had some chikoos and mangosteens. The number of chikoos and mangosteens left were the same after Fabian sold
34 of the chikoos and
47 of the mangosteens. If he had 84 chikoos at first,
- How many chikoos were left?
- How many mangosteens did Fabian have at first?

4x3 =
12 u |

3 u |
(a)
Fraction of the chikoos left
= 1 -
34 =
14 Fraction of the mangosteens left
= 1 -
47 =
37The number of chikoos and mangosteens left were the same. Make the number of chikoos and mangosteens left the same. LCM of 1 and 3 is 3.
Number of chikoos at first = 12 u
Number of mangosteens at first = 7 u
12 u = 84
1 u = 84 ÷ 12 = 7
Number of chikoos left
= 3 u
= 3 x 7
= 21
(b)
Number of mangosteens at first
= 7 u
= 7 x 7
= 49
Answer(s): (a) 21; (b) 49
