We can use the percent formula to solve. The percent formula is below: ^part⁄_whole = ^%⁄₁₀₀ First, we have to determine the part. In this problem, the part is the number of days the worker was late. We know from the problem that the worker showed up to work on time for 19 days. 20 days total - 19 days on time = 1 day late So, the part of the percent formula is 1. The whole of the percent formula (the total number of days) is 20. Now, we have to determine our percent. Since we we don't know the percent, this is where we are going to put our variable (x). ^part⁄_whole = ^%⁄₁₀₀ ¹⁄₂₀ = ^x⁄₁₀₀ Cross multiply and solve for x: ¹⁄₂₀ = ^x⁄₁₀₀ 20 * x = 1 * 100 20x = 100 20x/20 = 100/20 x = 5 So, 1 is 5% of 20.
