Question

a biology class examined some flowers in a local meadow. the students saw 87 perennial flowers and 13 annual flowers. what percentage of the flowers were perennials? write your answer using a percent sign (%).

Explanation:

Step1: Calculate total number of flowers

Total flowers = Perennial flowers + Annual flowers = \(87 + 13=100\)

Step2: Calculate percentage of perennial flowers

Percentage of perennial flowers = \(\frac{\text{Perennial flowers}}{\text{Total flowers}}\times100\%=\frac{87}{100}\times100\%\)
Since \(\frac{87}{100}\times100\% = 87\%\)

Answer:

\(87\%\)
