You need to get a common denominator
2 = (2*7)/7 = 14/7
So:
18/7+2= 18/7+14/7 = (18+14)/7 = 32/7
You can leave as 32/7 or you can write as:
32/7 = 4(4/7)
I hope this helps.

18 / 7 + 2 = 18/7 + 14/7 = 32/7 or 4 4/7

18/7 = 2 & 4/7
so
18/7 + 2 = 4 4/7

18/7 has a denominator of "7". Change "2" to a similar form by multiplying by "1" in the form "7/7". "2" is then 14/7. We then have: 18/7 + 14/7 or 32/7 => 4 4/7. Key point: when adding mixed numbers with different denominators, you need to transform them into similar numbers with equal denominators. Then perform whatever operation is need at that time.
