First you would change your mixed numbers into improper fractions.
So you have 74/9-43/6.
Now you must make both the denominators the same by multiplying 74/9 by
2/2 and 43/6 by 3/3.
This now gives you 148/18-129/18.
Now you simply subtract 148-129 which equals 19.
Almost done now that you have 19/18 just change it back into a mixed number 1 1/18.
Your answer is 1 1/18
