To find out how many students in a class of 30 scored between 80 and 90 percent on the last test, we need to calculate 20 percent of 30.
Step 1: Convert 20 percent to decimal form by dividing it by 100.
20/100 = 0.20
Step 2: Multiply the decimal form by 30 to find the number of students.
0.20 x 30 = 6
Therefore, 20% of the students in a class of 30 is 6 students.
