Help (fraction) problem :(

it's 8 4/6 because you have to make the denominator all 6 so you would have to mutiply the bottom and do the same for the top keep the whole number the same and then add it all up you'll get 8 4/6

3 1/6 that is your answer you're welcome.2 1/3=[(2*3)+1]/3=7/3

7/3+5/6=(7*2)/(3*2) + 5/6=(14+5)/6=19/6.You simplify and you get 3 1/6
