Answer:
There are 2500 girls
Step-by-step explanation:
So we have to show their ratio which is 4 : 5 = boys : girls
So then we sum them up to divide. 4 + 5 = 9
Since girls are 5 It'll be ![\frac{5}{9}*4500](https://tex.z-dn.net/?f=%5Cfrac%7B5%7D%7B9%7D%2A4500)
So let's multiply: ![\frac{22500}{9}](https://tex.z-dn.net/?f=%5Cfrac%7B22500%7D%7B9%7D)
girls: 2500
