In order to be allowed to go on a does trip, 80% of the students in a class must pads a pop quiz. If there are 26 students in the class. Approximately how many must pass the quiz?

Multiply:

0.8 * 26 = ?

To determine the approximate number of students who must pass the pop quiz in order for 80% of the class to pass, you need to follow these steps:

1. Calculate 80% of the total number of students in the class:
80% = 80/100 = 0.8
Number of students required to pass = 0.8 * 26 students = 20.8 students

2. Since we can't have a fraction of a student, we need to round up the number to the nearest whole number, as you can't have fractional students. In this case, since we can't have 0.8 of a student pass the quiz, we will round up to the nearest whole number.

Therefore, approximately 21 students must pass the pop quiz in order for 80% (or more) of the class to pass.
