A. 5 meals
B. 12 meals
C. 4 meals
D. 25 meals

Answer 1

Dan feeds his dog 2/5 pounds per meal and has 10 pounds of dog food. By dividing the total weight by the weight per meal, we find that the dog food will last for 25 meals.

Step-by-step explanation:

The question asks how many meals a 10-pound bag of dog food will last if Dan feeds his dog 2/5 pounds of food for each meal. To find the number of meals, divide the total amount of dog food by the amount given per meal. Therefore, the calculation to find the answer is 10 pounds divided by 2/5 pounds per meal.

1. Convert 2/5 pounds to a decimal: 2/5 = 0.4 pounds.
2. Divide the total pounds of dog food by the pounds per meal: 10 / 0.4 = 25 meals.

So, Dan's dog food will last for 25 meals.
