Corrina, this is the solution:
• Initial weight of the octopus = 5/6 kg
,• Weight the octopus gained in two weeks = 3/10 kg
,• Weight lost because of the sickness = 1/5 kg
In consequence, the current weight is:
5/6 + 3/10 - 1/5
Least commond denominator = 30
(25 + 9 - 6)/30 = 28/30
Simplifying:
• 14/15 kilograms is the current weight of the octopus
