We need to set up the problem this way...

15/180 = x/100

Cross multiply...

15 times 100 = 180x

8.33 percent

Check this by multiplying .0833 x 180 = 15 days absent

Answer: 18.75% or 1875%

step-by-step explanation:

is/of= 90/100 = 15/180 x %/100

15x100= 1500

1500/180 = 180x/80

1500÷80=18.75

x=18.75% or 1875%
