A=\frac{1}{2+\frac{23}{\frac{28}{7}-\frac{5}{7}}}
Convert 4 to fraction \frac{28}{7}.
A=\frac{1}{2+\frac{23}{\frac{28-5}{7}}}
Since \frac{28}{7} and \frac{5}{7} have the same denominator, subtract them by subtracting their numerators.
A=\frac{1}{2+\frac{23}{\frac{23}{7}}}
Subtract 5 from 28 to get 23.
A=\frac{1}{2+23\times \frac{7}{23}}
Divide 23 by \frac{23}{7} by multiplying 23 by the reciprocal of \frac{23}{7}.
A=\frac{1}{2+7}
Cancel out 23 and 23.
A=\frac{1}{9}
Add 2 and 7 to get 9.
