Answer»

Given expression:

$(4\frac{1}{2} + \left( {1 \div 2\frac{8}{9}} \right) - 3\frac{1}{{13}} = ?)$

$(\Rightarrow \;? = \frac{9}{2} + \left( {\frac{1}{{\frac{{26}}{9}}}} \right) - \frac{{40}}{{13}})$

$(\Rightarrow \;? = \frac{9}{2} + \frac{9}{{26}} - \frac{{40}}{{13}})$

$(\Rightarrow \frac{{117 + 9 - 80}}{{26}} = \frac{{46}}{{26}} = \;\frac{{23}}{{13}} = 1\frac{{10}}{{13}})$

HENCE, the required ANSWER is $(1\frac{{10}}{{13}})$
