我不識解下列題目: a a - - - = 1 4 8 P P - = - + 1 5 6 更新: 我需要祥細過程!
最佳解答:
1. (a/4) - (a/8) = 1 2a - a = 8....................both sides time 8 a = 8 // 2. (p/5) = (p/6) + 1 6p = 5p + 30................both sides time 30 p = 30 // 2007-02-25 11:01:41 補充： 如果閣下嫌唔夠詳細的話, 我用一個更詳細的方法解比你睇~1.( a/4 ) - ( a/8 ) = 1( a/4 )( 8 ) - ( a/8 )( 8 ) = 1( 8 )( 8a/4 ) - ( 8a/8 ) = 82a - a = 8a = 8 //2.( p/5 ) = ( p/6 ) + 1( p/5 )( 30 ) = ( p/6 )( 30 ) + 1( 30 )( 30p/5 ) = ( 30p/6 ) + 306p = 5p + 306p - 5p = 5p + 30 - 5pp = 30 // 2007-02-25 11:04:47 補充： 驗算一下~1. L.H.S. = (8/4) - (8/8)..........= 2 - 1..........= 1R.H.S. = 1L.H.S. = R.H.S.The answer ( 8 ) is correct.2.L.H.S. = (30/5) ..........= 6R.H.S. = (30/6) + 1......... = 5 + 1......... = 6L.H.S. = R.H.S.The answer ( 30 ) is correct.

1.a/4-a/8=1 2a-a=8 a=8 2.p/5=p/6+1 6p=5p+30 p=30 2007-02-26 13:01:25 補充： 驗算：１．８／４－８／８＝２－１＝１２．３０／５－３０／６＝６－５＝１
