How to Calculate Percentage
To calculate the percentage of one number to another, you can use the following formula:
Percentage = (Part / Whole) x 100%
In this case, we want to find the percentage of 400 to 430. So, we can plug these values into the formula:
Percentage = (400 / 430) x 100% = 93.02%
Therefore, 400 is 93.02% of 430.
