In a pie chart showing the preferences of students for different subjects, if Mathematics is represented by a segment of 30%, which of the following could be the total number of students surveyed if 90 students prefer Mathematics?
Step 1: Understand that 30% of the total number of students corresponds to the number of students who prefer Mathematics.
Step 2: Note that 30% is the same as 0.30 in decimal form.
Step 3: We know that 30% of the total number of students equals 90 students.
Step 4: Set up the equation: 0.30 * Total Students = 90.
Step 5: To find the total number of students, divide 90 by 0.30: Total Students = 90 / 0.30.
Step 6: Calculate the division: 90 divided by 0.30 equals 300.
Step 7: Conclude that the total number of students surveyed is 300.
