Answer:
10x + 4y is the correct answer
There are 80 children. 45 of them are girls. The amount of boys is equal to:
![80-45 = 35](https://tex.z-dn.net/?f=%2080-45%20%3D%2035%20)
That means there are 45 girls and 35 boys.
The ratio of boys to girls is: ![35:45](https://tex.z-dn.net/?f=%2035%3A45%20)
Simplify:
![35 \div 5 = 7 \\ 45 \div 5 = 9 \\ \\35:45 \rightarrow 7:9](https://tex.z-dn.net/?f=%2035%20%5Cdiv%205%20%3D%207%20%5C%5C%2045%20%5Cdiv%205%20%3D%209%20%5C%5C%20%5C%5C35%3A45%20%5Crightarrow%207%3A9%20)
Your answer is 7:9
