Answer: Your answer is -2 5/6
Step-by-step explanation:
Just convert the -2/3 to sixths. To do this, you multiply the denominator and numerator by 2 to make it equivalent to -2 1/6's denomenator (6). 2 times -2 is -4 and 3 times -2 is -6. This means -2/3 is equal to -4/6. As a result -2 1/6 - 4/6 is -2 5/6.

Answer:
1.2 gallons
Step-by-step explanation:
We assume that each room is rectangular with four walls and no doors. If the dimensions are length l, by width w with height h, then there are two walls with area l*h and two walls with w*h.
The total area of the room is thus: 2lh + 2wh = 2h(l+w).
l = 12ft, w = 12ft, h = 10ft (all given)
Area of walls = 2h(l+w) = 2*10(12+12)
Area = 2*10*24 = 480 square feet
Each gallon of paint covers 400 square feet. So, you will need to buy
480 / 400 = 1.2 gallons
You will need to buy 2 gallons
