In a pie chart showing the preferences of students for different subjects, if Mathematics is represented by a 90-degree angle, what percentage of students prefer Mathematics?
Step 1: Understand that a pie chart is a circle that represents data.
Step 2: Know that a full circle is 360 degrees.
Step 3: Identify that a 90-degree angle is part of the circle.
Step 4: Calculate what fraction of the circle 90 degrees is by dividing 90 by 360.
Step 5: Perform the calculation: 90 ÷ 360 = 1/4.
Step 6: Convert the fraction 1/4 into a percentage by multiplying by 100.
Step 7: Perform the calculation: (1/4) × 100 = 25%.
Step 8: Conclude that 25% of students prefer Mathematics.
