!!一條超簡單的問題!! 條題目係: 5 (-13)+(+12)-(--) 8 唔該大家如果識答就比埋步驟我啦~!! 多謝大家~!!
最佳解答:
-13 + (+12) - (-5/8) = -13 + 12 + 5/8 = 12 - 13 + 5/8 = -1 + 5/8 = -8/8 + 5/8 = (5-8)/8 = -3/8
-13 + (+12) - (-5/8) = -13 + 12 + 5/8 = 12 - 13 + 5/8 = -1 + 5/8 = -8/8 + 5/8 = (5-8)/8 = -3/8|||||-13 + (+12) - (-5/8) = -13 + 12 + 5/8 = 12 - 13 + 5/8 = -1 + 5/8 = -8/8 + 5/8 = (5-8)/8 = -3/8 答案是負8分之3。|||||(-13)+12-(-5/8) =(-1)+(5/8) =(3/8) 所以答案是3/8(八分之三)。 2006-12-31 17:37:31 補充: 對不起,答案有錯誤!(-13)+12-(-5/8)=(-1)+(5/8)=(-3/8)所以答案是-3/8(負八分之三)才對。|||||5 (-13)+(+12)-(--) 8 5 = -13+12+----- 8 3 = ------ or - 0.375 8|||||( - 13 ) + ( + 12 ) - ( - 5/8 ) = - 13 + 12 + ( 5/8 ) = - 1 + ( 5/8 ) = ( - 1 * 8 + 5 ) / 8 = ( - 8 + 5 ) / 8 = - 3 / 8|||||= -13+12+5/8 = -1+5/8 = -8/8+5/8 = -3/8|||||-3/8 負8份之3|||||-13 + (+12) - (-5/8) = -13 + 12 + 5/8 = 12 - 13 + 5/8 = -1 + 5/8 = -8/8 + 5/8 = (5-8)/8 = -3/8
