How to get 6 from the numbers {6, 7, 8, 9} using only addition, subtraction, division, and multiplication.

Is there a way you can get the number 6 from the numbers 6, 7, 8, and 9 using only addition, subtraction, multiplication, and division, without combining two numbers e.g. using the 6 and 7 to create 67. You may use parentheses and you can have to use each of the 4 numbers once.
