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(1)/(2)` pounds of grain to feed his farm animals

Each animal eats
`(3)/(4)` of a pound of feed

To find: number of animals he can feed

From given information,

Total pounds of grains =
`45(1)/(2) = (2 * 45 +1)/(2) = (91)/(2) \text{ pounds }`

One animal feeds =
`(3)/(4) \text{ pounds }`

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

`\rightarrow ((91)/(2))/((3)/(4))=(91)/(2) * (4)/(3)=(91 * 2)/(3)=(182)/(3)=60.66`

Thus he can feed 61 animals approximately
