Ally spent 15% of his time for cleaners, 10% for exercise, 20% of the remaining time to study. If he spent the remaining time for trip , retaining time is equal to which is decimal?
Let's assume Ally has a total of 100 units of time.
He spent 15 units of time for cleaners, which is 15% of 100.
He spent 10 units of time for exercise, which is 10% of 100.
The remaining time is 100 - 15 - 10 = 75 units of time.
20% of the remaining time is spent on studying, which is 20% of 75.
Therefore, he spent 15 units of time on studying.
The remaining time for the trip is 75 - 15 = 60 units of time.
To convert this to a decimal, we divide it by 100: 60/100 = 0.6.
Therefore, the decimal representation of the remaining time for the trip is 0.6.
