I don't understand ratios. How do you figure out just by knowing the 2 to 14 ratio.
adults = 2x
children = 14x
----
Equation:
2x + 14x = 320
16x = 320
x = 20
------
adults = 2x = 2*20 = 40
children = 14x = 14*20 = 280

Hi  

 Let x represent the constant of proportionality: adults 2x, children 14x

2x + 14x = 320

16x = 320

x = 20

Children: 2x = 2(20) = 40 children

Checking:

14x adults = 280

280 + 40 = 320 CHECKS!
