Answer:
825
Step-by-step explanation:
Let the number of students who participated in the sport be x, which is equivalent to 0.825
The total number of students in the school is equivalent to 1
Expressing mathematically,we obtain
0.825:x=1:1000

By cross multiplying we obtain,

We finally simplify to arrive at

Hence the number of students who participated in the sport is 825
Starting off with the base equation.

We want to rewrite the following equation

With d as a function of the other terms. Let's start by subtracting n from both sides.

Now, let's divide both sides by 9.

And this is our final answer.
