At eastwood middle school, 25% of the 60 sudents mrs. Wade teaches buy their lunches in the cafetria. How many students purchase

abruzzese [7]

Answer:

15 students purchase their lunches in the cafeteria.

Step-by-step explanation:

Given:

At eastwood middle school, 25% of the 60 students Mrs. Wade teaches buy their lunches in the cafeteria.

Now, to find the students purchase their lunches in the cafeteria.

Total students = 60.

Percent of students who buy lunches = 25%.

So, to get the number of students who buy their lunches in the cafeteria:

25% of 60.

$=\frac{25}{100} \times 60$

$=0.25\times 60$

$=15.$

Therefore, 15 students purchase their lunches in the cafeteria.
