Ok, there is an equation you can use to solve it.
n is a number.
p is also a number, but different to n.
![\frac { 7 }{ 9 } \cdot \frac { n }{ n } =\frac { p }{ p+12 } \\ \\ \frac { 7 }{ 9 } \cdot 1=\frac { p }{ p+12 } \\ \\ \frac { 7 }{ 9 } =\frac { p }{ p+12 }](https://tex.z-dn.net/?f=%5Cfrac%20%7B%207%20%7D%7B%209%20%7D%20%5Ccdot%20%5Cfrac%20%7B%20n%20%7D%7B%20n%20%7D%20%3D%5Cfrac%20%7B%20p%20%7D%7B%20p%2B12%20%7D%20%5C%5C%20%5C%5C%20%5Cfrac%20%7B%207%20%7D%7B%209%20%7D%20%5Ccdot%201%3D%5Cfrac%20%7B%20p%20%7D%7B%20p%2B12%20%7D%20%5C%5C%20%5C%5C%20%5Cfrac%20%7B%207%20%7D%7B%209%20%7D%20%3D%5Cfrac%20%7B%20p%20%7D%7B%20p%2B12%20%7D%20)
![\\ \\ 7\left( p+12 \right) =9p\\ \\ 7p+84=9p\\ \\ 9p-7p=84\\ \\ 2p=84\\ \\ p=\frac { 84 }{ 2 } \\ \\ p=42](https://tex.z-dn.net/?f=%5C%5C%20%5C%5C%207%5Cleft%28%20p%2B12%20%5Cright%29%20%3D9p%5C%5C%20%5C%5C%207p%2B84%3D9p%5C%5C%20%5C%5C%209p-7p%3D84%5C%5C%20%5C%5C%202p%3D84%5C%5C%20%5C%5C%20p%3D%5Cfrac%20%7B%2084%20%7D%7B%202%20%7D%20%5C%5C%20%5C%5C%20p%3D42)
Therefore:

![\frac { 7 }{ 9 } \cdot \frac { n }{ n } =\frac { 42 }{ 42+12 } =\frac { 42 }{ 54 } =\frac { 7 }{ 9 } \cdot \frac { 6 }{ 6 } \\ \\ \therefore \quad n=6](https://tex.z-dn.net/?f=%5Cfrac%20%7B%207%20%7D%7B%209%20%7D%20%5Ccdot%20%5Cfrac%20%7B%20n%20%7D%7B%20n%20%7D%20%3D%5Cfrac%20%7B%2042%20%7D%7B%2042%2B12%20%7D%20%3D%5Cfrac%20%7B%2042%20%7D%7B%2054%20%7D%20%3D%5Cfrac%20%7B%207%20%7D%7B%209%20%7D%20%5Ccdot%20%5Cfrac%20%7B%206%20%7D%7B%206%20%7D%20%5C%5C%20%5C%5C%20%5Ctherefore%20%5Cquad%20n%3D6)
So all together there were 54 girls and 42 boys in the theatre.
54 + 42 = 96
That's 96 children in total. (Answer)
7:9 = 42:54

Let's solve ~
Here, 6x is present on both the sides of equation so they cancel out ~ therefore there is no one solution satisfying the equation ~
