Question

A small animal can eat an amount of food that is equivalent to 2/5 it's body weight in 1/2 hour at this rate what fraction of its body weight in food can the animal eat in 1 hour

Answer 1

Explanation:

Think: 2/5 its body weight in 1/2 hour immediately becomes 4/5 its body weight in 1 hour. There's a proportional relationship here.

Answer 2

Answer:The fraction of food that the small animal can eat in one hour is 4/5

Explanation:

Let x represent the body weight of the small animal. The small animal can eat an amount of food that is equivalent to 2/5 it's body weight in 1/2 hour. This means that the quantity of food that the small animal can eat in 0.5 hours is 2x/5. Therefore, at the same rate, the amount of food that the animal can eat in one hour would be

2 × 2x/5 = 4x/5
