valeria surveys a different random sample of 50 students and finds that 18 of the students speak spanish at home. based on her sample, what percentage of students at the school speak spanish at home?
%

Explanation:

Step1: Calculate the percentage

The formula for percentage is $\frac{\text{number of students who speak Spanish}}{\text{total number of students surveyed}}\times100$.
For Valeria's sample, the number of students who speak Spanish is $18$ and the total number of students surveyed is $50$.
So the calculation is $\frac{18}{50}\times100$.

Step2: Simplify the fraction

$\frac{18}{50}=\frac{9}{25}$. Then $\frac{9}{25}\times100 = 9\times4$.

Answer:

$36$
