4/5 + 2/3 -11/8=

22/15 • 25/18 ÷ 44/9

(1/3 + 2/5) (5/6 - 3/4)​

Answer 1

Respuesta:

$\frac{4}{5} + \frac{2}{3} - \frac{11}{8} = \frac{12 + 10}{15} - \frac{11}{8} = \frac{22}{15} - \frac{11}{8} \\ = \frac{176 - 165}{120} = \frac{11}{120}$

$\frac{22}{15} \times \frac{25}{18} \div \frac{44}{9} = \frac{550}{270} \times \frac{9}{44} \\ = \frac{4950}{11880} = \frac{990}{2376} = \frac{330}{792 } = \frac{110}{264}$

$( \frac{1}{3} + \frac{2}{5} )( \frac{5}{6} - \frac{3}{4} ) = ( \frac{5 + 6}{15} )( \frac{20 - 18}{20}) \\ =( \frac{11}{15})( \frac{2}{20} ) = \frac{22}{300} = \frac{11}{150}$
