First we want to find the least common denominator of both fractions, and that would be 12.
Next we change the denominators and make them the same as the LCD 12
Next we want to join them together and make it 9 + 7 over 12
Now we want to make it 16/12 since 9 + 7 = 16 and 12 was already the denominator
Next we want to simplify the fraction 16/12 and make it 4/3.
And lastly we want to make 4/3 into a mixed fraction and we get the answer
Answer: 1 1/3
