Question

OPERAR Y DAR EL RESULTADO DE: M = (7/8) + (5/6) - (8/11) + (3/7) *

Answer 1

Respuesta:

$M\:=\:\left(\frac{7}{8}\right)\:+\:\left(\frac{5}{6}\right)\:-\:\left(\frac{8}{11}\right)\:+\:\left(\frac{3}{7}\right)\:$

Quitamos paréntesis

$\left(a\right)=a$

$M=\frac{7}{8}+\frac{5}{6}-\frac{8}{11}+\frac{3}{7}$

MCM de (8 - 6 - 11 - 7) = 1848

$M=\frac{1617}{1848}+\frac{1540}{1848}-\frac{1344}{1848}+\frac{792}{1848}$

$M=\frac{1617+1540-1344+792}{1848}$

$1617+1540-1344+792=2605$

$M=\frac{2605}{1848}$

Answer 2

Respuesta:

M = 5210 / 3696

simplificando seria :

2605 /1848

Explicación paso a paso:

M = (7/8) + (5/6) - (8/11) + (3/7)

M = [(7 x 6) + (8 x 5)]/(8 x 6) - 8/11 + 3/7

M = [ 42 + 40] /48 - 8/11 + 3/7

M = 82/48 -8/11 + 3/7

M = [(82 x 11) - (48 x 8)]/(48 x 11) + 3/7

M = [ 902 - 384]/528 + 3/7

M = 518/528 + 3/7

M = [(518 x 7) + (528 x 3)]/(528 x 7)

M = [3626 + 1584] / 3696

M = 5210 / 3696

simplificando seria :

2605 /1848
