You can think of a percentage as the part divided by the whole multiplied by 100.
For example if a company has 100 employees and 75 of them are women, if you want to calculate the percentage of women, 75 is the part, 100 is the whole.
75/100 = 0.75
Multiply that by 100 to get a percentage: 0.75 (100) = 75%.
For your problem 16,300 is the part. Let x represent the whole. Convert the percentage to a decimal by dividing by 100 (or moving the decimal point 2 places to the left). 24.8% is equivalent to 0.248.
So,
16300/x = 0.248
At this point there are few different ways to solve. You could convert 0.248 to a fraction (248/1000), then cross multiply. Or you could multiply both sides by x to reach this:
16300 = 0.248x (now divide both sides by the coefficient of x)
x = 16300/0.248 (about 65726 employees).
Another way to set up the equation is to translate the given info into an equation.
16300 IS 24.8% OF x. The word IS is translated as an equal sign, the work OF as multiplication.
16300 = 0.248 times x (24.8% converted to a decimal)
16300 = .0248x
x = 16300/0.248 (same result).
If you do convert the decimal to a fraction:
16300/x = 248/1000
248x = 16300(1000)
x = 16300(1000)/248
