This is an addition problem, so we need to find two equivalent fractions that have the same denominators. Then we can add the numerators together.
Re-writing the first fraction, we get 3/2.
List the multiples of each denominator until a common number is found.
Now we know 6 is the least common denominator of 3/2 and 2/3.
Re-writing the first fraction, we get 9/6.
Re-writing the second fraction, we get 4/6.
