Step-by-step explanation:
-2
To convert a mixed number to an improper fraction, you multiply the number in front of the fraction by the bottom number.
In this case, you will multiply 2 (because it is before the fraction) by 3 (because it is the bottom number of the fraction).
2 x 3 = 6
Then, you add 6 to the number on top.
6 + 2 = 8
Finally, you put 8 back onto the bottom number, ending up with -8/3.
