The temperature went from 83'F at noon to 72'F at midnight. What is the percent of decrease in the temperature from noon to midnight?
(83 - 72) / 83 = ?
Multiply the decimal answer by 100 to find the percent.
To find the percent decrease in temperature from noon to midnight, you need to calculate the difference between the two temperatures and then express it as a percentage of the initial temperature. Here's how you can do it:
1. Subtract the midnight temperature from the noon temperature:
83°F - 72°F = 11°F
2. Divide the temperature difference by the initial temperature:
11°F / 83°F = 0.1325 (rounded to four decimal places)
3. Multiply the result by 100 to convert it to a percentage:
0.1325 * 100 = 13.25%
Therefore, the percent of decrease in temperature from noon to midnight is approximately 13.25%.
