There are 4 cans of coke. Let's call this value A. So A = 4.

There are 16+4+18 = 38 cans of beverages. Let's call this B, so B = 38

Divide A over B to get A/B = 4/38 = 2/19

Using a calculator, 2/19 = 0.105263 approximately. This converts to 10.5263% after moving the decimal point 2 spots to the right.
