I think the easiest way is to get a common denominator. So I will show you that way. (another way is to change it from fractions to decimals).
So at first we have:
2/5 5/8 57/100
(57/100 comes from 0.57, since it is in the hundredths place you put it over 100)
The Least Common Multiple between 5, 8, and 100 is 200
2/5 = 2x40 and 5x40 = 80/200
5/8 = 5x25 and 8x25 = 125/200
57/100 = 57x2 and 100x2 = 114/200
So the answer would be: Sunday, Wednesday, Monday
