Let's first add the whole numbers:
2 + 4 = 6
The LCD of 1/2 and 2/3 is 3/6 and 4/6 . . .
3 + 4 = 7
(The denominators are equal in both fractions so they will remain the same)
= 7/6
Simplifying 7/6 . . .
7/6 = 1 1/6
6 + 1 = 7
7 + 1/6 = 7 1/6
7 1/6 ← answer
Your final answer is 7 1/6.
I hope this helps! :)
