Question

Mr. Keys has a herd of 250 cows on his 1,400 acre farm, and 4/5 of his cows have a calf at theirside. How many cows do not have a calf at their side?

Answer 1

We want to find the number of cows that do not have a calf at their side. For doing so, we remember that the total of cows that have a calf at their side is 4/5 of the total population, and thus, the number is given by:

`(4)/(5)(250)=(1000)/(5)=200`

This means that 200 cows have a calf at their side, and thus, just 50 cows do not have a calf at their side.
