Question

There is enough grass to feed six cows for three days. How long would the same amount of grass feed nine cows

Answer 1

2 days

Explanation:

Lets say that in one day, one cow eats 1 block of grass. So, six cows in three days would eat 18 blocks of grass in total. So 18 blocks of grass is how much we have. that means nine cows would eat that much in 2 days.
