Convert Fraction to Percent


Answer


Solution:

To find the percentage change from 75 to 90, we need to first calculate the difference between the two numbers.

Step 1: Difference = Final Value - Initial Value

Difference = 90 - 75

Difference = 15

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 = |15|

Absolute Difference = 15

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

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

Percentage Change = (15 / 75) x 100

Percentage Change = 20%

Therefore, the percentage change from 75 to 90 is 20%. This means that there was an increase of 20% from 75 to 90.
