Question

resolva a expressão a cima

Answer 1

{1/3 + [5 - (1/5 + 1/4 ) - (3 - 2  1/2)]} + (4   1/2 - 3) = 
{1/3 + [5 - (4/20 + 5/20 ) - (3 - 5/2)]} + (9/2 - 3) =
{1/3 + [5 - 9/20  -  (6/2-5/2) ] } + (9/2 - 6/2) = 
{1/3 + [ 5 - 9/20  - ( 1/2 )] + (3/2 ) = 
{1/3 + [5 - 9/20 - 1/2 ] + 3/2 = 
{ 1/3 + [100/20- 9/20 -10/20]+ 3/2 = 
{ 1/3 + [100/20 -19/20] +3/2 =
{ 1/3 + [81/20]} +3/2 =
{ 1/3 + 81/20} +3/2 =
m.m.c = 60
{20/60 + 81/60} +3/2 =
101/60 + 3/2 = 
m.m.c = 60
101/60 + 90/60 = 191/60
