Decrease

by

Example 1: What is the percent decrease from 32150 to 11600?

Using the formula,

${\displaystyle \mathrm{Percentage\; Decrease}=(1\mathrm{- }\frac{\mathrm{Final\; Value}}{\mathrm{Initial\; Value}})\times 100\%}$ ,

we have:

Initial Value = 32150

Final Value = 11600

We get

${\displaystyle \mathrm{Percentage\; Decrease}=(1\mathrm{- }\frac{\mathrm{11600}}{\mathrm{32150}})\times 100\%}$

Percentage decrease = 63.9191%

Example 2: What is the percent decrease from 90 to 75?

Using the formula,

${\displaystyle \mathrm{Percentage\; Decrease}=(1\mathrm{- }\frac{\mathrm{Final\; Value}}{\mathrm{Initial\; Value}})\times 100\%}$ ,

we have:

Initial Value = 90

Final Value = 75

We get

${\displaystyle \mathrm{Percentage\; Decrease}=(1\mathrm{- }\frac{\mathrm{75}}{\mathrm{90}})\times 100\%}$

Percentage decrease = 16.6666%

Example 1: Decrease the number 60 by 30%?

Using the formula,

${\displaystyle \mathrm{Decrease\; a\; Number\; by\; a\; Percentage}=(1-\frac{\mathrm{Percent\; value}}{100})\times \mathrm{original\; value}}$

we have:

Original Value = 60

Percent Value = 30

We get

${\displaystyle \mathrm{Decrease\; a\; Number\; by\; a\; Percentage}=(1-\frac{\mathrm{30}}{100})\times \mathrm{60}}$

Decreased value = 42

Example 2: Decrease the number 100 by 100%?

Using the formula,

${\displaystyle \mathrm{Decrease\; a\; Number\; by\; a\; Percentage}=(1-\frac{\mathrm{Percent\; value}}{100})\times \mathrm{original\; value}}$

we have:

Original Value = 100

Percent Value = 100

We get

${\displaystyle \mathrm{Decrease\; a\; Number\; by\; a\; Percentage}=(1-\frac{\mathrm{100}}{100})\times \mathrm{100}}$

Decreased value = 0
