題目係:
[(+ 2 /3 ) + ( -5/3 ) - ( -3/2 ) ] 除 [ ( - 1/2 + 1/3 ) ( - 6 ) ]
P.S : 2/3即係=三分之二...如此類推
唔該可唔可以遂個步驟解比我知?!因為我計極都唔計唔到...唔知D分數使唔使通分....如果得既..就寫埋個步驟!!唔該晒 ! Thank You ]]
好急架!!!!
正負數(混合) 一題數....急!!唔該幫下忙~

✔ 最佳答案
[(+ 2 /3 ) + ( -5/3 ) - ( -3/2 ) ] / [ ( - 1/2 + 1/3 ) ( - 6 ) ]=( 2/3 - 5/3 + 3/2 ) / [ ( -3/6 + 2/6 )( -6 )
=( 4/6 - 10/6 +9/6 ) / [ ( -1/6 )( -6 ) ]
=( 3/6 ) / ( 1 )
=3/6
=1/2

[(+ 2 /3 ) + ( -5/3 ) - ( -3/2 ) ] / [ ( - 1/2 + 1/3 ) ( - 6 ) ]
=( 2/3 - 5/3 + 3/2 ) / [ ( -3/6 + 2/6 )( -6 )
=( 4/6 - 10/6 +9/6 ) / [ ( -1/6 )( -6 ) ]
=( 3/6 ) / ( 1 )
=3/6
=1/2
=( 2/3 - 5/3 + 3/2 ) / [ ( -3/6 + 2/6 )( -6 )
=( 4/6 - 10/6 +9/6 ) / [ ( -1/6 )( -6 ) ]
=( 3/6 ) / ( 1 )
=3/6
=1/2

[( 2 /3 ) (-5/3 )-(-3/2 )]/[ (-1/2 1/3)(-6) ]
=[( 2/3)-(5/3) (3/2)]/[(-3 2)/6](-6)
=[( 4-10 9)/6]/[(-1)/6](-6)
=( 3/6)/1
=+1/2
=[( 2/3)-(5/3) (3/2)]/[(-3 2)/6](-6)
=[( 4-10 9)/6]/[(-1)/6](-6)
=( 3/6)/1
=+1/2
