Question

a biology class examined some flowers in a local meadow. out of the 36 flowers they saw, 9 were perennials. what percentage of the flowers were perennials? write your answer using a percent sign (%).

Explanation:

Step1: Calculate the percentage

The formula for percentage is $\frac{\text{part}}{\text{whole}}\times100\%$. Here, the part is the number of perennials ($9$) and the whole is the total number of flowers ($36$).
So, we have $\frac{9}{36}\times100\%$.

Step2: Simplify the fraction

Simplify $\frac{9}{36}$ to $\frac{1}{4}$.
Then, $\frac{1}{4}\times100\% = 25\%$.

Answer:

$25\%$
