To express the number of times the die landed on 6 as a fraction, you would take the number of times it landed on 6 and divide it by the total number of rolls.
In this case, the die landed on 6 a total of 7 times out of 12 rolls. Therefore, you can express this as a fraction:
\[ \frac{7}{12} \]
So, the number of times the die landed on 6 can be expressed as the fraction \(\frac{7}{12}\).
