Question

Angela and Ryou are painting a room. Angela has 2 1/2 gallons of blue paint and Ryou has half as much white paint. It will take 2 3/4 quarts to cover each wall. If each wall is painted only one color, how many walls will be blue and how many white? How much paint will be leftover?

Answer 1

Conversion from gallons to quarts

1 gallon = 4 quarts

Now,

Angela has 2 1/2 gallons = 2 1/2 * 4 = 10 quarts of blue paint

Ryou has 1/2 of what Angela has = 1.2 * 10 = 5 quarts of white paint

Each wall requires 2 3/4 quarts of paint
After coloring:
blue colored walls= (10)(2 3/4)= 3 walls with 7/11 quarts of paint remaining
white colored walls= (5)(2 3/4)= 1 wall with 9/11 quarts of paint remaining
