Question

A small animal can eat an amount of food that is equivalent to 2/5 its body weight in ½ hour. At this rate what fraction of its body weight in food can the animal eat in 1 hour?

Answer 1

Answer:

4/5 of its body weight

Answer 2

Given that a small animal can eat an amount of food that is equivalent to $\frac{2}{5}$ its body weight in $\frac{1}{2}$ hour.

TO FIND :

The rate at what fraction of its body weight in food can the animal eat in 1 hour.

SOLUTION :

From the given a small animal can eat an amount of food that is equivalent to $\frac{2}{5}$ its body weight in $\frac{1}{2}$ hour can be written as

$Amount of food a small animal can eat=\frac{2}{5}$ its body weight in $\frac{1}{2}$ hour.

The fraction of its body weight in food can the animal eat in 1 hour is given by

$\frac{2}{5}+\frac{2}{5}=\frac{1}{2}+\frac{1}{2}$ for 1 hour

$\frac{4}{5}=1 hour$

Rewritting the above equation we get

$1 hour=\frac{4}{5}$

Therefore The fraction of its body weight in food can the animal eat in 1 hour is $\frac{4}{5}$
