Ok, there is an equation you can use to solve it.
n is a number.
p is also a number, but different to n.
Therefore:

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
I believe it is 60 since they are oppsites, but i am not so good at math so someone should probably check my work
(8/9) / (1/4) =
8/9 * 4/1 =
32 / 9 =
3 5/9 ........she can make 3 5/9 one-fourth cup servings
84/4=21
now take the 2 even numbers below 21 and the 2 even numbers above 21
18 +20 + 22 +24 = 84
the numbers are 18, 20, 22 & 24
