​ can be simplified by dividing both the numerator and the denominator by their greatest common factor, which is 3:

Step 4: Add the remaining fraction

Now add To add fractions, you need a common denominator. The least common denominator of 2 and 4 is 4.

Convert ​ to a fraction with a denominator of 4:

Now, you can add ​:

Step 5: Convert back to a mixed fraction (if needed)

27 divided by 4 equals 6 with a remainder of 3. Therefore
