edward took a survey and found that 3 out of every 5 students in his class walk to school. if there are 25 students in his class, how many students can be expected to walk to school?

(3/5) * (25/1) = 75/5 = 15

To determine the number of students who can be expected to walk to school, we need to calculate 3/5 of the total number of students in Edward's class.

Step 1: Find the number of students who walk to school.
Multiply the total number of students (25) by the fraction representing the proportion of students who walk to school (3/5).
Number of students who walk to school = 25 * (3/5)

Step 2: Simplify the fraction.
Multiply the numerator (3) by the total number of students (25), and then divide the result by the denominator (5).
Number of students who walk to school = (3 * 25) / 5

Step 3: Perform the multiplication and division.
Number of students who walk to school = 75 / 5

Step 4: Calculate the final answer.
Division of 75 by 5 gives us the result.
Number of students who walk to school = 15

Therefore, based on Edward's survey, we can expect that 15 students in his class will walk to school.
