# CLASS-6FINDING DECREASED PERCENTAGE

FINDING DECREASED PERCENTAGE -

To calculate the decreased percentage, you need to find the percentage decrease between two values. Here's how you can do it:

Decreased Percentage = ((Old Value - New Value) / Old Value) * 100

[Where, Old Value < New Value]

Where:

• Old Value:- The initial value before the decrease.
• New Value:- The value after the decrease.

Let's work through an example:

Example.1) Suppose the temperature was initially 80 degrees Fahrenheit, and after cooling, it became 60 degrees Fahrenheit. Calculate the decreased percentage in temperature.

Ans.)

Old Value = 80 degrees Fahrenheit
New Value = 60 degrees Fahrenheit

Decreased Percentage = ((80 - 60) / 80) * 100 = (20 / 80) * 100 = 0.25 * 100 = 25%

So, the temperature decreased by 25%.     (Ans.)

Example.2) Suppose the temperature was initially 80 degrees Fahrenheit and it decreased to 60 degrees Fahrenheit. Calculate the decreased percentage.

Ans.) Old Value = 80°F
New Value = 60°F

Decreased Percentage = ((80 - 60) / 80) * 100 = (20 / 80) * 100 = 0.25 * 100 = 25%

So, the temperature decreased by 25%.     (Ans.)

Example.3) Suppose the temperature was initially 80 degrees Fahrenheit, and after some cooling, it became 60 degrees Fahrenheit. Calculate the decreased percentage.

Ans.) Old Value = 80°F
New Value = 60°F

Decreased Percentage = ((80 - 60) / 80) * 100 = (20 / 80) * 100 = 0.25 * 100 = 25%

So, the temperature decreased by 25%.    (Ans.)
