Mrs. Ebert feeds her dog 1/3 of a cup of dog food twice each day. How long will 6 cups of dog food last?
A 18 days
B 2 days
C 4 days
D 9 days
Each day, Mrs. Ebert feeds her dog 1/3 cup of dog food + 1/3 cup of dog food = 2/3 cup of dog food.
Each day, Mrs. Ebert uses 2/3 cup of dog food * 2 = 4/3 cup of dog food.
Over 6 cups of dog food / 4/3 cup dog food per day = <<6/(4/3)=4.5>>4.5 days.
This means the dog food will last for a little more than 4 days.
The answer is C) 4 days.
To find out how long 6 cups of dog food will last, we need to determine how much dog food is consumed each day.
We know that Mrs. Ebert feeds her dog 1/3 of a cup of dog food twice each day, which means the dog consumes 1/3 + 1/3 = 2/3 of a cup of dog food each day.
To find out how many days 6 cups of dog food will last, we divide the total amount of dog food by the amount consumed each day:
6 cups / (2/3 cups per day) = 6 cups * (3/2 cups per day) = 18 days
So, 6 cups of dog food will last Mrs. Ebert's dog 18 days.
Answer: A) 18 days
To determine how long 6 cups of dog food will last, we need to find out how many 1/3 cup servings of dog food there are in 6 cups.
Mrs. Ebert feeds her dog 1/3 of a cup of dog food twice each day. So, each day, the dog eats 1/3 cup + 1/3 cup = 2/3 cup of dog food.
To find out how many days 6 cups of dog food will last, we need to divide 6 cups by 2/3 cup.
Dividing a whole number by a fraction can be done by multiplying the whole number by the reciprocal of the fraction.
So, let's convert the fraction 2/3 into its reciprocal, which is 3/2.
Now we can multiply 6 cups by 3/2:
6 cups × 3/2 = (6 × 3) / 2 = 18 / 2 = 9
Therefore, 6 cups of dog food will last for 9 days.
Answer: D 9 days
