Finding a common denominator between 10 and 12 to be 10*12=120, we can multiply 9/10 by 12/12 and 3/12 by 10/10 to get 108/120 and 30/120 respectively. Dividing the 2 (as we want to know how much 3/12 or 30/120 goes into 9/10 or 108/120), we get
(108/120)/(30/120)=(108/120)*(120/30)=(108/30)=3+18/30 (as 30 goes into 90 3 times and 108-90=18)
Because of this statement, x + y = a as well.

<span>With five houses every three hours, Brianna will paint 20 houses in 12 hours. 12 hours / 3 hours = 4 'rounds'. 5 houses * 4 rounds = 20 houses.
With three houses every four hours, Nicholas will paint 9 houses in 12 hours. 12 hours / 4 hours = 3 'rounds'. 3 houses * 3 rounds = 9 houses.
So Brianna will paint 20 - 9 more houses than Nicholas, or 11 houses more.</span>
