if there were n pieces, you know that

1/6 n = 2
n = 12
Think of it like this. Your goal is to make an equivalent fraction with the denominator 2. In this case, just times both sides by 2 to get 12 slices.
If your need to draw a picture, make a circle, and divide it into 6 pieces. Shade in one before you continue. Now, because there were 2 slices left, divide each piece into 2.
