Answer: [tex]\frac{9}{16}[/tex]
Step-by-step explanation:
We need to find the ratio of girls to the total number of students. That means our ratio is going to be 72 (the number of girls) over 56+72 (boys + girls, the total number of students).
When you add 56+72, you'll get 128 in the denominator. Continuing to simplify the fraction, you'll end up with:
[tex]\frac{72}{128}[/tex] = [tex]\frac{9}{16}[/tex]
Depending on what format your teacher wants, this can be written as [tex]\frac{9}{16}[/tex] or 9:16.
