Three investors own a company. One partner owns One-fourthof the company, while the second partner owns Two-fifths of the company. How much does the third partner own? Two-thirds

Answer 1

1 - 1/4 - 2/5 = 1 - 5/20 - 8/20 = 1- 13/20 = 7/20

the 3rd partner has a 7/20 share

2/3 = 40/60

7/20 = 21/60

Not really close, off by 19/60, but maybe "close" in some sense. If you were buying out the 3rd partner, check his numbers, he's likely selling at an excessive price.
