Hello from MrBillDoesMath!
Answer: 40%
Discussion:
Let's ask an easier question. What is 1/2 or 50% of the number 150?. It's 75. Since 75 is larger than the problem's 60 we need to look for a slightly smaller percentage than 50%. The choice of 40% seems evident.
Another approach:
60 = (x/100) 150
so x = (60/150) * 100 = 40 %

Total 52 students.
52 - 17 = 35 students left
35 - 5 = 30 students left
30 - 2 = 28 students left
Each class has 11 students that play ONE sport, which means 22 total in 2 classes. You're on your own now! It's not that hard, I'm sure you'll figure it out.
(leftover = land - house) area
7x*11x - 2x*3x = 77x -6x
left= 77x^2
What do you need help with?
