Questions & Step-by-Step Solutions
A pie chart shows the percentage of students enrolled in different courses. If 30% of students are in Science, what fraction of students are not in Science?
Step 1: Understand that the total percentage of students is 100%.
Step 2: If 30% of students are in Science, we need to find out how many are not in Science.
Step 3: Subtract the percentage of students in Science from the total percentage: 100% - 30% = 70%.
Step 4: This means 70% of students are not in Science.
Step 5: To convert 70% into a fraction, remember that 70% means 70 out of 100, which is written as 70/100.
Step 6: Simplify the fraction 70/100 by dividing both the numerator and the denominator by 10, which gives us 7/10.
Step 7: The fraction of students not in Science is 7/10.
