12/9 reduced in simplest form would be 4/3 or 1 1/3. You can pick which one you want to do :). They are both the same thing just one is an improper fraction and the other is a mixed number. I got this answer by dividing both the top and the bottom (The denominator and the numerator) by three.
You'd start off by adding the 2 adults together (10.75 + 10.75) which would equal 21.50 dollars. Now you take the three kids together (5.50 +5.50+5.50) which would equal 16.50 dollars. Now you just take the 16.50+21.50 and add those together---- 38 dollars
