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?

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

Just tell koda to adjust the number of shapes himself.
