[tex] (\frac{11}{12} - \frac{7}{15} ) \times \frac{10}{9} + \frac{1}{2} = \frac{9}{20} \times \frac{10}{9} + \frac{1}{2 } = \frac{1}{2} + \frac{1}{2} = 1[/tex]

sper ca te-am ajutat!=))

[tex]( \frac{11}{12} - \frac{7}{15} ) \times \frac{10}{9} + \frac{1}{2 } = [/tex]

[tex] (\frac{55}{60} - \frac{28}{60} ) \times \frac{10}{9} + \frac{1}{2} = [/tex]

[tex] \frac{27}{60} \times \frac{10}{9} + \frac{1}{2} = [/tex]

[tex] \frac{270}{540} + \frac{1}{2} = [/tex]

[tex] \frac{270}{540} + \frac{270}{540} = [/tex]

[tex] \frac{540}{540} = \frac{1}{1} = 1[/tex]
