The ratio of non athletes at Browns Primary School is 3:4. If there are 225 athletes, how Many non athletes are there

x/225 = 3/4

The ratio is apparently only approximate, or there is a typo.
In fact, I know it, because you say "ratio of non athletes" which is meaningless.

To find the number of non-athletes at Browns Primary School, we can use the given ratio and the number of athletes.

The ratio of non-athletes to athletes is 3:4, which means for every 3 non-athletes, there are 4 athletes.

Given that there are 225 athletes, we can set up the following proportion:

3 non-athletes / 4 athletes = N non-athletes / 225 athletes

To solve for N (the number of non-athletes), we can cross-multiply and then divide:

4N = 3 * 225

4N = 675

N = 675 / 4

N ≈ 168.75

Since the number of non-athletes must be a whole number, we can round this to the nearest whole number:

N ≈ 169

Therefore, there are approximately 169 non-athletes at Browns Primary School.
