    a-b = 2 a/b= 2.22222222(repeating) or to make it more simple, a/b= 2 and two-ninths

    right so we have: \[a-b=2 \\ \frac{a}{b}=\frac{20}{9}\] You can solve the first equation for a by saying a=2+b now replace the a in the second equation with 2+b

    \[\frac{2+b}{b}=\frac{20}{9}\] solve for b
