First step is correct but the working steps are wrong. U have to make the denominator the same number. Multiply the bottom, multiply the top. From then u can minus the top

No the answer will be 1/10 th of people like swimming.
The difference as described in the book is wrrong.
It will be 2/5+1/2=9/10
Then subtract it from 1
1-9/10=1/10
