Answer 2

$( \frac{11}{12} - \frac{7}{15} ) \times \frac{10}{9} + \frac{1}{2 } =$

$(\frac{55}{60} - \frac{28}{60} ) \times \frac{10}{9} + \frac{1}{2} =$

$\frac{27}{60} \times \frac{10}{9} + \frac{1}{2} =$

$\frac{270}{540} + \frac{1}{2} =$

$\frac{270}{540} + \frac{270}{540} =$

$\frac{540}{540} = \frac{1}{1} = 1$
