Just need help don't understand it

9(THIS IS WRON PLEASE REFER TO SOMEONE ELSE)

Step-by-step explanation:

f is an unknown variable so we can ignore it for now, basically we need to put the first 2 into an improper fraction and simplify later. doing this gives us 6/5 and 11/4  we then give these the same denominato and we can do this by multiplying 6/5 by 4 and multiplying 11/4 by 5. this gives us 24/ 20 + 55/20. we add that to get 79/20 and simplify that to 3 and 19/20. we add the 3 to the 6 and get 9. Hope this helped

12 11/20 f

Step-by-step explanation: We will ignore the variable (f) for now. First make these fractions improper. Next give them the same denominator by multiplying 6/5 by 4 and 11/4 by 5. Now we have 4 4/5 and 13 3/4 Simplified in simplest form. Now we add them and get 18 11/20. Now we have to subtract 6 from 18 11/20. Make 18 11/20 into improper fraction. 371/20 is the improper fraction. Now make 6 into a fraction. 371/20 - 6/1 equals 251/20. You will have to simplify it. The simplified fraction is 12 11/20... So the final answer is 12 11/20 f. Hope this helps... If it doesn't let me know. Stay safe and have a great rest of the day... :D
