12

Step-by-step explanation:

The LCM of both 9 and 10 is 90. First, we want to not have a mixed number, so we change each fraction to 74/9 and 41/10. Now, we multiply to get 740/90 and 369/90. Adding these, we get 1109/90. Since 1109 is a prime number, we can't factor it. However, we can estimate it to the nearest number. 1109/90 is approximate to 12.
