(4/22 + 1/11) : (23/25 x 5/13)
(4/22 + 2/22) : (115/325)
6/22 : 115/325
3/11 : 23/65
3/11 x 65/23
195/253

( \frac{4}{22} + \frac{1}{11} ) : ( \frac{23}{25} x \frac{5}{13} )
= ( \frac{4}{22} +  \frac{2}{22} ) : ( \frac{23}{5} x \frac{1}{13} )
= ( \frac{6}{22} ) : ( \frac{23}{65} )
=  \frac{6}{22} x  \frac{65}{23}
=  \frac{390}{506} (disederhanakan di bagi 2)
=  \frac{195}{253}
