Answer:
17 boys : 28 girls
Step-by-step explanation:
we know that
Part-to-part ratios provide the relationship between two distinct groups
Let
x ----> the number of boys of the Henley Middle School Drama Club
y ----> the number of girls of the Henley Middle School Drama Club
we know that
[tex]x+y=45[/tex]
[tex]x=45-y[/tex] ----> equation A
[tex]y=28[/tex] ----> equation B
substitute equation B in equation A and solve for x
[tex]x=45-28=17[/tex]
therefore
There are 17 of boys and 28 girls at the Henley Middle School Drama Club
A part-to-part ratio is
17 boys : 28 girls
