Answer:
Almost!
Explanation:
Problems 1-9 and 11 are correct, but not problem 10 or 12
For problem 10, 12/6 does equal 6/1, so it would just be the whole number of 6 as your final answer as it doesn't need to be simplified further.
For problem 12, -4/6 can be simplified further to -2/3 by dividing by 2.
