(a)
The number of puffs that Henry and Asher each had in the end is the same. Make the number of puffs that Henry and Asher each had in the end the same. LCM of 3 and 1 is 3.
Number of puffs that Henry had less than Asher at first
= 6 u - 5 u
= 1 u
1 u = 6
1 u = 6 ÷ 1 = 6
Number of puffs that Henry had at first
= 5 u
= 5 x 6
= 30
(b)
Total number of puffs that the 3 of them bought
= 5 u + 6 u + 3 u + 6
= 14 u + 6
= 14 x 6 + 6
= 84 + 6
= 90
Answer(s): (a) 30; (b) 90
