1) [1/5 + 1/3 + 1/2] / [4/5] = [(6 + 10 + 15) / 30] / [4/5] = [31/30] / [4/5] = [31*5] / 30*4] =
= 31/24 = 1.2916....
2) [3/2 + 1/4 + 5/8 + 3/16] / [-1/4] = [(24 + 4 + 10 + 3) / 16 ] / [-1/4]= [41/16] / /[-1/4] =
= -[41*4]/[16] =-41/4 = 10.25
= 31/24 = 1.2916....
2) [3/2 + 1/4 + 5/8 + 3/16] / [-1/4] = [(24 + 4 + 10 + 3) / 16 ] / [-1/4]= [41/16] / /[-1/4] =
= -[41*4]/[16] =-41/4 = 10.25

(1/5 + 1/3 + 1/2):(4/5)
(1/5 + 1/3 + 1/2) = (6 + 10 + 15) / (30) ; mcm(5,3,2) = 5*3*2 = 30
= 31/30
(31/30):(4/5) = (5*31)/(4*30)
= 155/120
simplificando entre 5:
155/120 = 31/24
(3/2 + 1/4 + 5/8 + 3/16): (-1/4)
(3/2 + 1/4 + 5/8 + 3/ 16) = (8*3 + 4*1 + 2*5 + 1*3)/(16); mcm(2,4,8,16) = 16
= (24 + 4 + 10 + 3) / (16)
= 41/16
(41 / 16) / (-1/4) = (4)*(41) / (-1)*(16)
= (-164)/16
simplificando dividiendo entre 2
(-164 / 16) = -82/8 = -41/4
(1/5 + 1/3 + 1/2) = (6 + 10 + 15) / (30) ; mcm(5,3,2) = 5*3*2 = 30
= 31/30
(31/30):(4/5) = (5*31)/(4*30)
= 155/120
simplificando entre 5:
155/120 = 31/24
(3/2 + 1/4 + 5/8 + 3/16): (-1/4)
(3/2 + 1/4 + 5/8 + 3/ 16) = (8*3 + 4*1 + 2*5 + 1*3)/(16); mcm(2,4,8,16) = 16
= (24 + 4 + 10 + 3) / (16)
= 41/16
(41 / 16) / (-1/4) = (4)*(41) / (-1)*(16)
= (-164)/16
simplificando dividiendo entre 2
(-164 / 16) = -82/8 = -41/4
