I need formula's for figuring out % problems. example 7 is what percent of 4
or %125 of what is 85?
or 22.2% of 45 is ?
To calculate percentages, you can use the following formulas:
1. Finding the value of a percentage: To find what percent one number is of another number, use the formula:
Percentage = (Part / Whole) * 100
Let's take your first example: "7 is what percent of 4?"
Percentage = (7 / 4) * 100
Percentage = 175%
So, 7 is 175% of 4.
2. Finding the value when given a percentage: To find what value a certain percentage represents of another number, use the formula:
Value = (Percentage / 100) * Whole
For your second example: "%125 of what is 85?"
Value = (125 / 100) * 85
Value = 106.25
So, 125% of 85 is 106.25.
3. Finding the percentage of a number: To find a certain percentage of a given number, use the formula:
Percentage Value = (Percentage / 100) * Number
In your third example: "22.2% of 45 is?"
Percentage Value = (22.2 / 100) * 45
Percentage Value = 9.99
So, 22.2% of 45 is 9.99.
Remember to adjust the formula and apply the appropriate math operations based on your specific scenario.
