Answer: Tony had 7/30 hours (7 over 30) hours left to complete it.

Explanation:

To find the answer, you have to find a like denominator. So the denominator with the least value is 30. So we multiply 9 by 3 and 10 by 3 to get 27/30. Next, you multiply 2 by 10 and 3 by 10 to get 20/30. Then you subtract 27/30 and 20/30 to get 7/30.

If this helped you let me know. If not, I will improve and make sure my work is correct. Have a nice day!
