Question
If the temperature dropped in 3 days is 27 degrees. Temperature dropped in a day is __________.
- 0
- 11
- 9
- 10
Hint:
The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.
The correct answer is: 9
We have to find the temperature drop per day if there was temperature drop of 27 degrees in 3 days.
Temperature drop in 3 days = 27°.
So, temperature drop in 1 day = 27/3 = 9°.
Hence, the correct option is C.
Temperature drop per day multiplied by number of days gives the total temperature drop.
