To find out how long 6 cups of dog food will last, we need to calculate the number of times Mrs. Ebert feeds her dog per cup of dog food.
Mrs. Ebert feeds her dog 1/3 of a cup of dog food twice each day.
So, in one day, she feeds her dog 1/3 + 1/3 = 2/3 cups of dog food.
To find out how many days 6 cups of dog food will last, divide 6 by 2/3:
6 ÷ 2/3 = 6 × 3/2 = 18.
Therefore, 6 cups of dog food will last Mrs. Ebert's dog for 18 days.
The answer is: 18 days.
To find out how long 6 cups of dog food will last, we need to determine how much dog food Mrs. Ebert's dog consumes each day and then divide that amount into 6 cups.
Mrs. Ebert feeds her dog 1/3 of a cup of dog food twice each day. So, the dog consumes a total of 1/3 + 1/3 = 2/3 of a cup of dog food each day.
To calculate how many days 6 cups of dog food will last, we need to divide 6 by 2/3.
To divide a number by a fraction, we need to multiply it by the reciprocal of the fraction. So, 6 / (2/3) is the same as 6 * (3/2).
Multiplying 6 by 3/2, we get (6 * 3) / 2 = 18 / 2 = 9.
Therefore, 6 cups of dog food will last 9 days.
