Question

(DECIMALES)
Me ayudan a calcular el valor de B porfa

Answer 1

Respuesta:

0.6666....=$\frac{6}{9}=\frac{2}{3}$

1.3333.....=$\frac{13-1}{9}=\frac{12}{9}=\frac{4}{3}$

0.2151515....=$\frac{215-2}{990}=\frac{213}{990}=\frac{71}{330}$

2.5=$\frac{5}{2}$

0.875=$\frac{7}{8}$

ENTONCES:

$\frac{\frac{2}{3}-\frac{5}{2}}{\frac{7}{8}-\frac{4}{3}}-\frac{71}{330}=\frac{\frac{19}{6} }{\frac{-11}{24}}-\frac{71}{330}=\frac{456}{-66}-\frac{71}{330}=\frac{-2351}{330}$
