Dominic's Ice Creamery sold 50 sundaes last week. There were nuts on 11 of the sundaes. What is the ratio of the number of sundaes without nuts to the number of sundaes with nuts? Write your answer as two numbers separated by a colon (for example, \( 2: 3 \) ).

1. Total number of sundaes is \(50\), and the number of sundaes with nuts is \(11\). 2. Compute the number of sundaes without nuts by subtracting: \[ 50 - 11 = 39 \] 3. Form the ratio of the number of sundaes without nuts to the number with nuts: \[ 39:11 \] Thus, the answer is \(39:11\).
