4.02*35的简便算法
4.02*35的简便算法
4.02*35的简便算法
4.02*35
=2.01×(35×2)
=2.01×70
=140.7
4.02*35
=4×35+0.02×35
=140+0.7
=140.7
4.02×35=(4+0.02)×35
=4×35+0.02×35
=140+0.7=140.7
4.02 分成4+0.02 然后分配率吧
4*35+0.02*35=140+0.7=140.7
4.02×35
= 35×(4+0.02)
=140 + 0.7
=140.7
就是4×35+35÷50=140.7
(4+0.02)*35=4*35+0.02*35=140+0.7=140.7
你好,爱拍雪兰
答案:
4.02*35
=(4+0.02)×35
=4×35+0.02×35
=140+0.7
=140.7
