How to Calculate Percentage Decrease Manually?
Find percentage decrease between two numbers becomes straightforward using the above-shared formula. Here are a few examples that will enable you to learn the method of calculating percentage decrease manually using the formula.
Percentage Decrease Example 1:
The original price of a book was $20. The business owner announced a discount on the books, and the new price of the pen is now $10. What is the percent decrease in the book price?
Solution:
Old Price of Book: $20
New Price of Book: $10
Enter the values in the percent decrease formula:
Percentage decrease: [(Old Value - New Value) / Old Value] × 100
= [(20-10)/20] x 100
= [10/20] x 100
= 0.5 x 100
= 50%
So, the percent decrease in the price of book is 50%.
Percentage Decrease Example 2:
Bella averaged 80 mph driving on the highway. But, while returning during rush hour, she averaged 50 mph. What is the % decrease in her rate of travel?
Solution:
Initial Speed: 80 mph
Final Speed: 50 mph
Enter the values in the percent decrease formula:
Percentage decrease: [(Initial Value – Final Value) / Initial Value] × 100
= [(80-50)/80] x 100
= [30/80] x 100
= 0.375 x 100
= 37.5%
So, Bella travelled 37.5% more slowly on her second trip.
Percent Decrease Example 3
Alex scored a 90 on her first Physics test and a 74 on her second Physics test. Find the percentage decrease between test scores?
Solution:
Old Test Score: 90
New Test Score: 74
Enter the values in the percentage decrease formula:
Percentage decrease: [(Old Value - New Value) / Old Value] × 100
= [(90-74)/90] x 100
= [16/90] x 100
= 0.117 x 100
= 17.77%
So, the rate of percentage decrease between Alex's test scores was 17.77%.
Percent Decrease Example 4:
The price of apples is $12 per Kilogram in the summer season and $8 per Kilogram in the winter season then calculate the percentage decrease in the price of apples.
Initial price = $12
Final price = $8
Enter the values in the formula for percentage decrease:
Percentage decrease: [(Old Value - New Value) / Old Value] × 100
= [(12-8)/12] x 100
= [4/12] x 100
= 0.333 x 100
= 33.33%
Percentage decrease of apples prize = 33.33333%
