Question

números fracionários com expressões complexas
(1-1/2)^2/[(1-3/4)x8+(1/2)^2]

Answer 1

( 1/1 - 1/2)² / [ (1/1-3/4) * 8/1 + ( 1/2)² ]

(1/1 - 1/2)² =  ( 2 - 1)/2 = ( 1/2)² = 1/4
( 1/1 - 3/4 ) = ( 4 -3)/4 =  ( 1/4)
REESCREVENDO
( 1/4 ) / [ ( 1/4) * 8/1 + ( 1/4) ]
( 1/4) / [ ( 8/4) + ( 1/4) ]
( 1/4) / [  ( 2/1) + ( 1/4)]
( 1/4) /[ ( 8 + 2)/4 ]
( 1/4 ) / ( 10/4 )
1/4 * 4/10 = 4/40 = 1/10 ****
