Question

como se calcula esto: 8/5-(3/4+6/20)

Answer 1

Resolver.

$\frac{8}{5} - ( \frac{3}{4} + \frac{6}{20})$

$\frac{8}{5} - ( \frac{3*5}{4*5} + \frac{6}{20})$

$\frac{8}{5} - ( \frac{15}{20} + \frac{6}{20})$

$\frac{8}{5} - \frac{15+6}{20}$

$\frac{8}{5} - ( \frac{21}{20})$

$\frac{8*4}{5*4} - \frac{21}{20}$

$\frac{32}{20} - \frac{21}{20}$

$\frac{32-21}{20}$

$\frac{11}{20}$
