Answer:
Step-by-step explanation:
**Solution:**
Let the three parts be represented by x, y, and z.
According to the given information, we have:
(x : y : z = frac{1}{3} : frac{1}{5} : frac{1}{9} = 5 : 3 : 1)
This means that the parts are in the ratio 5 : 3 : 1.
Let the parts be 5x, 3x, and x respectively.
According to the question, the sum of these parts is equal to 4000:
5x + 3x + x = 4000
[9x = 4000]
[x = frac{4000}{9}]
[x = 444.44]
Therefore,
The three parts are:
1st part = 5x = 5 * 444.44 = 2222.22
2nd part = 3x = 3 * 444.44 = 1333.33
3rd part = x = 444.44
