your answer is 5/6.
1. make the denominators the same as the LCD
1/6+(2*2/3*2)
2. simplify. denominators are now the same
1/6+4/6
3. join the denominators
1+4/6
4. simplify
5/6
tell me if u have any more questions

Its max is 780.

2/3 + 1/6 = 5/6

So if you do 650/5=130 then add up,

650+130=780. Your answer is 780.
