Given the statement:
A class has a ratio of boys to girls of 3/4
Explanation:
Since it is stated that the ratio of boys to girls is ¾, it is the same as 3:4, hence it can be confirmed that the ratio of boys 3, and the ratio of girls is 4, hence ¾ is the fraction of boys in the class. For example, we set the number of boys = 9 and girls = 12, since their ratio is proportional, if we take 9/12 it is the same as ¾, hence we can determine how many boys there are in class.
