Questions & Step-by-Step Solutions
In a class of 30 students, if 10 students have a negative attitude, what percentage of the class has a negative attitude?
Step 1: Identify the total number of students in the class. In this case, there are 30 students.
Step 2: Identify the number of students with a negative attitude. Here, there are 10 students with a negative attitude.
Step 3: To find the percentage, divide the number of students with a negative attitude (10) by the total number of students (30). This gives you 10/30.
Step 4: Calculate the division: 10 divided by 30 equals 0.3333.
Step 5: To convert this decimal into a percentage, multiply by 100. So, 0.3333 * 100 equals 33.33.
