Three investors own a company. One partner owns 1/4 of the company , while the second partner owns 2/5 of the company . How much does the third partner own ?
We want to add these together and then subtract from one. So to add them, find a common denominator. The closest common denominator is 20. So convert the fractions: 5/20 and 8/20 Then add 5/20 + 8/20 = 13/20 And then subtract from 1. 1 - 13/20 = 7/20 The third partner owns 7/20 of the company.
multiply 1/4 by 5/5 and 2/5 by 4/4 and you will get 5/20 and 8/20 and add them together and you get 13/20. Subtract 13/20 from 1 (20/20) and you get 7/20
