Question 982576
Let's say there are 30 teachers. Two-thirds of them is (2/3)*30 = (2*30)/3 = 60/3 = 20. So 20 teachers own a house. The remaining 30 - 20 = 10 teachers don't own a house.



ratio of non-homeowners to homeowners = (non-owners) : (owners)


ratio of non-homeowners to homeowners = 10:20


ratio of non-homeowners to homeowners = 1:2



Which effectively says "there are twice as many owners as there are non-owners"
