Question

Consider the problem: After charging for 1/3 of an hour, a phone is at 2/5 of its full power. How long will it take the phone to charge completely?

Answer 1

Base on the given ratio, it will take the phone 5/6 hours to charge completely

How to determine the time to charge completely?

The given parameter can be represented as:

Ratio = Time : Proportion

So, we have:

Ratio = 1/3 : 2/5

To charge fully, we have:

Time : 1 = 1/3 : 2/5

Express as fraction

Time/1 = 1/3/ 2/5

Evaluate

Time = 5/6

Hence, it will take the phone 5/6 hours to charge completely
