There are 48 students in a school play. The ratio of boys to girls is 5:7. How many boys are in the school play? Explain how you

mr Goodwill [35]

Boys: x
gilrs: y

From the text of the task:

$\left \{ {{\frac{x}{y}=\frac{5}{7}} \atop {x+y=48 \rightarrow x=48-y}} \right.$

Replacing x:

$\frac{48-y}{y}=\frac{5}{7}\\
\\
7(48-y)=5y\\
\\
336-7y=5y\\
\\
12y=336\\
\\
y=\frac{336}{12}=28$

So there are 28 girs and 20 boys
