Answer 1

Answer: A 1 quart yellow, 2 quarts blue, 3 quarts white

Explanation:

if u divide 480 by 80 you will get 6 so u will only need 6 quarts of paint.

Answer 2

Answer and explanation:

Since a quarter(1/4) of paint covers 80 square feet, a whole paint would cover 80×4= 320 square feet of the wall

Remaining part of the wall left unpainted after using one whole paint

480-320= 160 square feet

Therefore paint required for remaining unpainted part

= 160/80= 2 quarters of paint(1/4+1/4)= 1/2 paint

Total paint required for the wall = one whole paint + half paint = 1+1/2= 1 1/2

Total paint required is one and half

Or

We divide area of wall by area of wall covered by each quarter

480/80=6 quarters of paint

6 quarters of paint = 1/4+1/4+1/4+1/4+1/4+1/4

We still get same answer

= 1 1/2
