Answer 1

Hi there! The answer is 18 pieces.

There are 3 first grade classes and each class has 22 students in it. Therefore there are 3 × 22 = 66 students.

If there are 66 students and each student needs 2 pieces of red paper, there is a total need of 2 × 66 = 132 pieces of red paper.

There are 150 pieces of red paper and there is a total need of 132 of these pieces. Therefore there are 150 - 132 = 18 pieces of red paper left.

The answer is 18 pieces.
