They probably want you to cancel out common factors to reduce the fraction they provided.
Notice that 6 can be written in prime factor form as 2 * 3 (2 times 3)
Then when we use the fraction form as shown below, a common factor of 2 in numerator and denominator can be cancelled out:
[tex]\frac{6}{2}=\frac{3\cdot2}{2}=3[/tex]Then your answer is an integer number: 3
