I would set up a proportion:
The proportion basically says, "if there are 5 kids meals for every 4 adult meals, that means 20 kids meals would mean x adult meals." Just cross multiply and then solve for x:
That means there are 20 kids meals sold and 16 adult meals sold, so the result is:
36 meals in total.
