Convert Fraction to Percent


Answer


Solution:

To find the percentage change from 120 to 80, we need to first calculate the difference between the two numbers.

Step 1: Difference = Final Value - Initial Value

Difference = 80 - 120

Difference = -40

Step 2: Next, we need to find the absolute value of the difference. This is because percentage change is always calculated as a positive value.

Absolute Difference = |Difference|

Absolute Difference = |-40|

Absolute Difference = 40

Step 3: Now, we can calculate the percentage change using the formula:

Percentage Change = (Absolute Difference / Initial Value) x 100

Percentage Change = (40 / 120) x 100

Percentage Change = 33.33%

Therefore, the percentage change from 120 to 80 is -33.33%. This means that there was a decrease of 33.33% from 120 to 80.
