Answer:
A. DEF=EDF
Step-by-step explanation:
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.
