23/5+28/6

To add fractions with different denominators, you need to find a common denominator. In this case, the least common multiple (LCM) of 5 and 6 is 30.

Now, let's convert the fractions:

23/5 = (23 * 6) / (5 * 6) = 138/30 28/6 = (28 * 5) / (6 * 5) = 140/30

Now that both fractions have the same denominator, you can add them:

138/30 + 140/30 = (138 + 140) / 30 = 278/30

The resulting fraction is 278/30.
