Question

EJERCICIO C)
[11/7 . (1/7 - 5/2) -7 ] . 3/4

Answer 1

Respuesta:

$\boxed{\left[\frac{11}{7}\cdot \left(\frac{1}{7}-\frac{5}{2}\right)-7\right]\cdot \frac{3}{4}}$

$\mathrm{Calculamos:}$

$\left[\frac{11}{7}\cdot \left(\frac{1}{7}-\frac{5}{2}\right)-7\right]$

$\left(\frac{1}{7}-\frac{5}{2}\right)=-\frac{33}{14}$

$\frac{11}{7}\left(-\frac{33}{14}\right)=-\frac{363}{98}$

$-\frac{363}{98}-7=-\frac{1049}{98}$

$\frac{1049}{98}\cdot \frac{3}{4}=\frac{1049\cdot \:3}{98\cdot \:4}$

$-\frac{1049\cdot \:3}{98\cdot \:4}$

$\mathrm{Multiplicamos:}$

$1049\cdot \:3=3147$

$98\cdot \:4=392$

Solución:

$\boxed{-\frac{3147}{392}}$
