Question

resuelve el ejercicio2/3-2/9-(1/6-1/15)-(7/45+3/10)=​

Answer 1

Respuesta:

22/45

Explicación:

$\frac{2}{3} - \frac{2}{9} - ( \frac{1}{6} - \frac{1}{15} ) - ( \frac{7}{45} + \frac{3}{10} ) =$

$\frac{2}{3} - \frac{2}{9} - ( \frac{5 - 2}{30} ) - ( \frac{14 - 27}{90} ) =$

$\frac{2}{3} - \frac{2}{9} - ( \frac{3}{30} ) - ( \frac{ - 13}{90} ) =$

$\frac{2}{3} - \frac{2}{9} - \frac{1}{10} + \frac{13}{90} =$

$\frac{60 - 20 - 9 + 13}{90} =$

$\frac{44}{90} = \frac{22}{45}$
