Question

Mr McDonald has 45 1/2 pounds of grain to feed his farm animals. If each animal eats 3/4 of a pound of feed, how many animals can he feed?

Answer 1

Donald can feed 61 animals approximately

Solution:

Given that Donald has $45\frac{1}{2}$ pounds of grain to feed his farm animals

Each animal eats $\frac{3}{4}$ of a pound of feed

To find: number of animals he can feed

From given information,

Total pounds of grains = $45\frac{1}{2} = \frac{2 \times 45 +1}{2} = \frac{91}{2} \text{ pounds }$

One animal feeds = $\frac{3}{4} \text{ pounds }$

number of animals he can feed = Total pounds of grains divided by one animal feeds

$\rightarrow \frac{\frac{91}{2}}{\frac{3}{4}}=\frac{91}{2} \times \frac{4}{3}=\frac{91 \times 2}{3}=\frac{182}{3}=60.66$

Thus he can feed 61 animals approximately
