Question

What is the percent of decrease from 80 to 60

Answer 1

25% decrease

Explanation:

To find percent of increase/decrease you can do the following:

take the difference of new and original values, divide it by the original value - this will give you a decimal

Multiply the decimal by 100 to change to a percent

So, (60-80) ÷ 80 = -20/80 which is -1/4 or -.25

25% decrease

the result will always be negative if there's a decrease in values and positive if there is an increase in before and after values

Answer 2

25% decrease

Explanation:

percent decrease is calculated as

`(decrease)/(original)` × 100%

decrease = 80 - 60 = 20 and original value = 80 , then

percentage decrease =
`(20)/(80)` × 100% =
`(1)/(4)` × 100% = 0.25 × 100% = 25%
