Find the whole using the percent equation.

Question

20 patients is 80% of what number of patients?

Answer 1

Let's call the whole number of patients X.

According to the percent equation, we can set up the equation:

20 = 0.8X

To find the value of X, divide both sides of the equation by 0.8:

20/0.8 = X

X = 25

Therefore, 20 patients is 80% of 25 patients.
