A farmer has a flock of 20 sheep. He has 15 white
sheep, 4 brown sheep, and 1
black sheep. What is the
percentage of brown sheep in his flock?
To find the percentage of brown sheep in the farmer's flock, we need to divide the number of brown sheep by the total number of sheep in the flock.
Total number of sheep = 20
Number of brown sheep = 4
Percentage of brown sheep = (Number of brown sheep / Total number of sheep) * 100
= (4 / 20) * 100
= 0.2 * 100
= 20%
Therefore, the percentage of brown sheep in the farmer's flock is 20%.
