Question

Mieko bought 2 gallons of paint. She used 1/4 of the paint in her bedroom, 3 quarts in the hallway, and the rest of the paint in the living room. How many quarts of paint did she use in the living room?

A: 3 Quarts

B. 8 Quarts

C. 10 Quarts

D. 12 Quarts

Answer 1

Answer: 3 quarts (choice A)

=======================================================

Step-by-step explanation:

1 gallon = 4 quarts

2 gallons = 8 quarts

1/4 of 8 quarts = 2 quarts

She used 2 quarts for her bedroom and 3 for the hallway. Therefore, she used 2+3 = 5 quarts total.

That leaves 8 - 5 = 3 quarts for the living room.

Answer 2

A: 3 Quarts

Step-by-step explanation:

1 gallon = 4 quarts

1/4 of 2 gallons = 1/4 × 2

= 1/2 gallon

⇒ 1/2 gallon = 2 quarts

Therefore, Mieko used 2 quarts of paint to paint her bedroom.

If she used 3 quarts to paint the hallway, then

⇒ total number of quarts used = 2 + 3 = 5 quarts

As she bought a total of 2 gallons of paint:

⇒ 2 gallons = 2 × 4 = 8 quarts

Therefore the remaining unused paint (to paint the living room) is:

⇒ total paint - used paid = 8 quarts - 5 quarts

= 3 quarts
