Cows will graze the same field in 9 days ?
​

Answer 1

Answer:

44 cows---Number of cows needed to

graze the field in 9 days.

Step-by-Step Explanation:

Let x=number of cows needed to graze the field in 9 days

If 33 cows can graze a field in 12 days, then one cow can graze the field in 33*12=396 days. This means that one cow grazes at the rate of 1/396 fields per day;33 cows graze at the rate of 33/396=1/12 field per day

X Cows graze at the rate of x/396 fields per day and we are told that this equals 1/9 fields per day, soooooo

x/396=1/9

9x=396

x=44 cows---Number of cows needed to

graze the field in 9 days.
