Now we get the equation : 1 1/3y - 2/3 + 6/9y + 1 1/9
2- finding common denominators 1 1/3y and 6/9y can both have 9 as the denominator . The fraction 1/3 has to be multiplied by 3 , both numerator & denominator , to get the same denominator (sorry if it’s confusing) .
Then we’d get 1 3/9y + 6/9y = 2y
Now we do the same thing with the other digits (without a variable)
