if there are 21 blonde students in a chemistry class of 65 students, what is the percentage of blonde students in the class? report your answer to three significant figures:
3.09%
none of these
309%
0.323%
32.3%

Explanation:

Step1: Calculate the ratio of blonde students

To find the percentage, we first find the ratio of blonde students to total students, which is $\frac{21}{65}$.

Step2: Convert the ratio to a percentage

Multiply the ratio by 100 to get the percentage: $\frac{21}{65} \times 100 \approx 32.3077\%$.

Step3: Round to three significant figures

Rounding 32.3077% to three significant figures gives 32.3%.

Answer:

32.3%
