Question

efectúa estas operaciones.
11/6 -(1/4 +1/6) x6
(3/7+1/2 ) x 6/5-2
4/9: (5/3 - 1/6 )+ (-1/4 )
(2 - 1/2 ) : (4 + 1/3 ) x (-6/5)

Answer 1

1) 11/6 - (1/4 + 1/6) · 6 = 22/12 - (3+2/12) · 6 = 22/12 - 5/12 · 6 = 17/12 · 6 = 102/12 = 51/6 = 17/2

2) (3/7 + 1/2) · 6/5 - 2 = (6+7/14) · 6/5 -2 = 13/14 · 6/5 -2 = 78/70 - 140/70 = -62/70 = -31/35

3) 4/9 : (5/3 - 1/6) + (-1/4) = 4/9 : (10-1/6) -1/4 = 4/9 : 9/6 - 1/4 = 24/81 - 1/4 = 96-81/324 = 15/324 = 5/108

4) (2 - 1/2) : (4 + 1/3) · (-6/5) = (4-1/2) : (12+1/3) · (-6/5) = 3/2 : 13/3 · (-6/5) = 9/26 · (-6/5) = -54/130 = -27/65
