Answer: The ratio of boys to girls would be 3 : 5 .
Step-by-step explanation:
Since we have given that
Number of boys and girls = 32
Fraction of boys are going on a field trip =
Fraction of girls are going on a field trip =
Number of children left = 9
Let the number of boys be 'b'.
Let the number of girls be 'g'.
According to question, it becomes ,
From eq(1), we get that g = 32-b
So, it becomes,
so, number of girls would be 32 - b = 32 - 12 = 20
So, Ratio of boys to girls in class would be 12 : 20 = 3 : 5.
Therefore, the ratio of boys to girls would be 3 : 5 .
