These statistics are impossible: all students who ride bike and use crossing guard ride a bike, so the proportion of students who ride a bike and use the crossing guard must be less than or equal to the proportion of students who ride a bike. This is not true in the given stats; 0.12 > 0.1
5/8 of the total has been sold, so we just do 64*5/8=40 houses that had been sold this year. Hope this helped!
Answer:

Dividing the 9 times n by 9 gives us the following:
9n÷7
