If you have 25 cases of led for a led pencil, and your friend has 1/5 cases less than you. You give them 1/3 of your 25 cases of led to your friend. How many cases of led does your friend have at the end of the day?
Your friend has (4/5) (25) = 20 at first
(1/3)(25) = 25/3 cases
20 + 25/3 =
60/3 + 25/3 =
85/3 cases
