percentage

Question

Yesterday, the high temperature was 80 degrees Fahrenheit. Today,  the high temperature was 75 degrees Fahrenheit. What is the percent decrease in the high temperatures from yesterday to today?

Answer 1

First, you must find the actual decrease in temperature.

 

Decrease = Yesterday's temperature - Today's temperature

Decrease = 80 - 75

Decrease = 5 degrees

 

Now, find the percentage decrease.

 

% Decrease = Actual decrease / Yesterday's temperature x 100

% Decrease = 5/80 x 100

% Decrease = 0.0625 x 100

% Decrease = 6.25 %

 

So, the percent decrease in high temperature from yesterday to today is 6.25%.

Answer 2

you can do decreased temperature divided by the original which shows you the decimal .9375

multiply the decimal by 100 to turn this into a percentage 93.75 % which shows you that 75 is only 93.75 % of the number 80. if you subtract 93.75% from 100, 100-93.75 = 6.25, you see that the temperature decreased by 6.25%.
