Jeanette has 33 coins in her coin collection. 16 of the coins are gold and the rest are silver. What is the ratio of the number of silver coins to the number of gold coins?

Write your answer as a fraction. Use a slash ( / ) to separate the numerator and denominator.

There are 33 - 16 = <<33-16=17>>17 silver coins.

Thus, the ratio of silver coins to gold coins is 17/16. Answer: \boxed{17/16}.
