Answer:
1 and 36/45
Step-by-step explanation:
First, you have to make the denominators the same so that you can add them.
The smallest number that both 15 and 9 are factors of is 45.
Since you had to multiply 15 by 3 to get 45, you need to multiply 7 by 3 as well. this leaves with the fraction 1 21/45.
You multiplied 9 by 5 to get 45 so now you need to multiply 3 by 5 as well leaving you with the fraction 15/45.
Now all you have to do is add 1 21/45 + 15/45.
15 + 21 = 36 leaving you with your answer:
1 36/45
Hope this helps!
