1樓:思考創新成功
等於2.5×0.6-0.6×0.15=0.6×(2.5-0.15)=0.6×0.1=0.06
所以結果等於0.06
2樓:肇東的回憶
2.5×0.6-1.8×0.5
=2.5×0.6-(0.6×3)×0.5
=2.5×0.6-0.6×(3×0.5)
=2.5×0.6-0.6×1.5
=0.6×(2.5-1.5)
=0.6×1
=0.6
3樓:匿名使用者
2.5ⅹ0.6-1.8x0.5
=2.5x0.6-0.6ⅹ3x0.5
=0.6x(2.5-1.5)
=0.6x1
=0.6
脫式計算2.5x0.6一1.8x0.5
4樓:亦安研
2.5x0.6一1.8x0.5
=2.5×0.6-0.6×1.5
=0.6×(2.5-1.5)
=0.6
