Answer 2

Firstly, we have to find the LCD, or lowest common denominator, of 1/9 and 2/3. We can find this by listing all the multiples of 9 and 3. In this case, the LCM is 9. Multiply 1/9 by 1/1 and 2/3 by 3/3:

$\frac{2}{3} \times \frac{3}{3}=\frac{6}{9}\\\\\frac{1}{9}\times\frac{1}{1}=\frac{1}{9}\\\\ \frac{6}{9}+y-\frac{1}{9}=\frac{7}{9}$

Now subtract 1/9 from 6/9: $\frac{5}{9} +y=\frac{7}{9}$

Now subtract 5/9 from 7/9 and your answer will be $y=\frac{2}{9}$
