{(10000-8000)/10000}x100=(?). 10000 to 8000 percent decrease provides the comprehensive information on how to find what is the percent of decrease from 10000 to 8000.

__10000 to 8000 percent increase__

(10000 - 8000)/10000 x 100 = (?)

= 2000/10000 x 100

= 20%

(10000 - 8000)/10000 x 100 = 20%

Hence,

the percent of decrease from 10000 to 8000 is 20%

__where,__

10000 is the base or reference quantity,

8000 is the relative or decreased quantity,

2000 is the difference between base and decreased quantity,

20% is the percent decrease.

The result of difference between the reference quantity 10000 and decreased quantity 8000 divided by the reference quantity 10000, multiplied with 100 is the percent of decrease from 10000 to 8000. The below is the step-by-step work shows how to find what is the percent of decrease from 10000 to 8000 by using the mathematical formula.
step 1 Observe the input parameters, values and what to be found:

__Input values:__

Base or reference value X = 10000

Decreased or relative value Y = 8000

__What to be found:__

Find the percent of decrease from 10000 to 8000.

(8000 - 10000)/60 x 100 = (?)%

step 2 Find the difference between reference quantity 10000 and decreased quantity 8000:

10000 - 8000 = 2000

step 3
Divide the difference 2000 by the reference quantity 10000, and multiply the result with 100:

2000/10000 x 100 = 20%

Hence,

20% is the percent of decrease from 10000 to 8000.
