Just plug in
Assuming there are 100 employees

25% are PT = 25
75% FT = 75

Assume that the total number of hrs FT employees have to work = 10
PT will work = 3/5*10 = 6

since the wages are same , there will no affect on ratios
total number of hrs FT employees work = 75*10 = 750
PT = 25*6 = 150

now the ratio is 150/900 = 1/6
