Step-by-step explanation:
let the third part = x
second part = 4/5 * x
first part = 3/4 *4/5 * x = 3/5 * x
first part + second part + third part = 60
3/5*x + 4/5*x + x = 60
3x + 4x + 5x = 60
5
12x = 60 * 5
x = 60 * 5
12
third part x = 25
second part = 4/5x = 4 * 25 = 20
5
first part = 3/5 * x = 3 * 25 = 15
