Answer:
![15\ girls](https://tex.z-dn.net/?f=15%5C%20girls)
Step-by-step explanation:
Let
x-----> the number of girls
y-----> the number of boys
we know that
-----> equation A
![\frac{x}{y}=\frac{5}{4}](https://tex.z-dn.net/?f=%5Cfrac%7Bx%7D%7By%7D%3D%5Cfrac%7B5%7D%7B4%7D)
isolate the variable y
-----> equation B
Substitute equation B in equation A
![x+\frac{4}{5}x=27](https://tex.z-dn.net/?f=x%2B%5Cfrac%7B4%7D%7B5%7Dx%3D27)
![\frac{9}{5}x=27](https://tex.z-dn.net/?f=%5Cfrac%7B9%7D%7B5%7Dx%3D27)
![x=5*27/9=15\ girls](https://tex.z-dn.net/?f=x%3D5%2A27%2F9%3D15%5C%20girls)
