To start this question you have to find out how much one cow eats in one day.
630kg ÷ 18days = 35kg per day
35kg ÷ 14cows = 2.5kg per cow per day
Then you must find out how much hay must eaten per day.
770kg ÷ 28days = 27.5kg per day
Then divide 27.5 by 2.5 to find the amount of cows needed.
27.5kg ÷ 2.5 = 11
11 cows will eat 770kg of hay in 28 days
