The ratio of girls to boys in Liza’s classroom is 5 to 4. How many girls are in her classroom if there is a total of 27 students

andrezito [222]

Answer:

$15\ girls$

Step-by-step explanation:

Let

x-----> the number of girls

y-----> the number of boys

we know that

$x+y=27$ -----> equation A

$\frac{x}{y}=\frac{5}{4}$

isolate the variable y

$y=\frac{4}{5}x$ -----> equation B

Substitute equation B in equation A

$x+\frac{4}{5}x=27$

$\frac{9}{5}x=27$

$x=5*27/9=15\ girls$
