Note: The second and third calculators both calculate the same thing (percent). They are just worded differently.
All of these calculators use the same general equation:
A/100 x B = C
where A, B, and C are defined by:
A% of B = C
If you know any two of the variables (A, B, C) you can solve for the third unknown variable.
Taking the general equation: A/100 x B = C and rearranging:
A = (C / B) x 100
B = C / (A / 100)
C = (A / 100) x B
Note: A% = A/100 because % means per 100
Alternatively, the Percentage Calculator on the home page can be used to answer
percentage problems like the examples above by choosing which box you want to be the answer box. Click the round button below the variable you need to find and it will become the answer box. Enter the two known variables into the blue boxes and the answer will be calculated.
