We finally simplify to arrive at

Hence the number of students who participated in the sport is 825

825 students

Step-by-step explanation:

When we say 0.825 students participate, we are actually meaning that 82.5% of the students are participating.

Note: to get decimal to percentage, we move the decimal 2 places right

In total there are 1000 students, so we need to find 82.5% of them to find the number who participate in a sport.

Note: To get this, we need to multiply 1000 by the DECIMAL of 82.5%, which is 0.825.

Hence, we have 1000 * 0.825 = 825 students
