To find how many sixth graders there are we need to find out how many students there are in 1/5 in the school. Divide 200 by 2 to find 1/5 of the school.
Since 3/5 of the school is 6th graders we multiply 100 by 3 to find that there are 300 students in the 6th grade.

x = 10

Step-by-step explanation:

In the last step, you can see that the fraction \frac{1}{5} has been multiplied by its reciprocal \frac{5}{1}, making it cancel out. The reciprocal has been multiplied to both sides, so all you need to do is multiply \frac{6}{3} · \frac{5}{1} :

6 · 5 = 30

3 · 1 = 3

<u><em>So now you should have the fraction:</em></u>

x = \frac{30}{3}

<u><em>But, you can still simplify the fraction by dividing 30 by 3:</em></u>

x = 10
