Answer:
80%
Step-by-step explanation:
The percentage change is calculated from ...
percent change = ((new)/(old) -1) × 100%
= (72/40 -1) × 100%
= (1.8 -1) × 100%
= 80%
The second value is 80% greater than the first.
We have been given that during one period extreme cold, the average daily temperature decreased degree F each day. We are asked to find number of days it will take for the temperature to decrease by 9 degree F.
First of all we will convert our mixed fraction into improper fraction.
Now we will divide total temperature change (9) by average daily temperature change () to find number of days.
Dividing a number by a fraction is same as multiplying the number by reciprocal of the fraction.
Therefore, it will take 6 days for the temperature to decrease by 9 degree F.
