kifflom [539]

Answer:

512

Step-by-step explanation:

Let the number of 7th graders in the school is x.

As three-quarters of them play at least one sport, so, the number of 7th graders who play sport = $\frac 3 4 x$ .

Among the 7th graders who play sports, half of them play more than one sport. So, the number of 7th graders who play more than one sport $= \frac 1 2\times \frac 3 4 x=\frac 3 8 x$ .

Among the 7th graders who play more than one sport, one-third of them play more than two sports. So, the number of 7th graders who play more than two sport $= \frac 1 3\times \frac 3 8 x=\frac 1 8 x$ .
