Question

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?

Answer 1

First, let's get a common denominator in the two fractions that we are given.


`(1)/(4) = (5)/(20)`


`(2)/(5) = (8)/(20)`

Add the two and you get
`(13)/(20)`

Therefore,
`(7)/(20)` is remaining and that is how much the third partner owns.

Answer 2

first you have to add 1/4 + 2/5 by finding a common denominator.
so you end up with:
13/20

Then subtract that from 20/20 (which is 1)
and get 7/20 as your answer

hope this helps
