Answer:
300 non atheletes
Step-by-step explanation:
Data obtained from the question include:
Ratio of athletes = 3
Ratio of non atheletes = 4
Total ratio = 3 + 4 = 7
Number of atheletes = 225
Number of non atheletes =?
To begin our calculations, let us obtain the total number of people present. This is illustrated below:
Let the total number of people present be T.
Number of athletes = ratio of athletes / tota ratio x T
3/7 x T = 225
Cross multiply to express in linear form
3T = 7 x 225
Divide both side by the coefficient of T i.e 3
T = (7 x 225) /3
T = 525
Therefore there are 525 people present.
Remember that the people present are atheletes and non atheletes i.e
Total = atheletes + non atheletes
Total = 525
Atheletes = 225
Non atheletes =?
Total = atheletes + non atheletes
525 = 225 + non atheletes
Collect like terms
Non atheletes = 525 - 225
Non atheletes = 300.
Therefore, there are 300 non atheletes present in the sch
