Question

A) 1/2 gallon
B) 1 gallon
C) 2 gallons
D) 1 1/2 gallon

Answer 1

To calculate how much paint Edwin used for the mural in his garage, we subtract the amount of paint he used for his bedroom from the total amount of paint he has. Edwin has 3 1/2 gallons of paint and used 2/3 of it for his bedroom, leaving him with 7/6 gallons for the mural in his garage. This is equal to 1 1/6 gallons.

Step-by-step explanation:

To find out how much paint Edwin uses for the mural in his garage, we need to subtract the amount of paint he used to paint his bedroom from the total amount of paint he has. Edwin started with 3 1/2 gallons of green paint and used 2/3 of it for his bedroom. So, we can calculate this by multiplying the total amount of paint by 2/3: 3 1/2 * 2/3 = 7/2 * 2/3 = 14/6 = 7/3 gallons.

Therefore, Edwin used 7/3 gallons of paint for his bedroom. To find out how much paint is left for the mural in his garage, we subtract the amount used for the bedroom from the total amount of paint: 3 1/2 - 7/3 = 21/6 - 14/6 = 7/6.

So, Edwin has 7/6 gallons of paint left for the mural in his garage. When simplified, this is equal to 1 1/6 gallons. Therefore, the answer is D) 1 1/2 gallon.
