Answer:
it will last 18 days
Explanation:
divide 42 by 2 1/3
2 1/3 = 7/3
42 / 7/3 =
42 * 3/7 =
126/7 = 18
if this isn't enough then here
The number of days it will take the dog to consume the 42 cup of food will be 18 days.
Total cups of dog food = 42 cups
Amount of cups consumed per day =
To obtain the number of days it will take to consume the entire food :
Divide the total amount of food by the amount consumed per day
Hence,
(42 ÷ (7/3))
Take the reciprocal of 7/3 and change the operation sign to multiplication
42 × 3/7 = (42 × 3) / 7 = 126 / 7 = 18 days
Therefore, it will take the dog 18 days to finish up the 42 cups of food.
