问题描述:
123*456/78/456*789/123=?* 表示乘号 / 表示除号
答
123×456÷78÷456×789÷123
=(123÷123)×(456÷456)×(789÷78)
=789÷78
=10余9
如果前面那个78是789,那么结果就是1
答
123*456/78/456*789/123=(123/123)*(456/456)/78*789=789/78
答
123*456/78/456*789/123
=123/123*456/78/456*789
=1*456/78/456*789
=456/456/78*789
=1/78*789
=263/26
答
123*456*(1/78)*(1/456)*789*(1/123)=789/78
我估计你写错了,分母也应该是789,因此最后答案是1
答
123*456/789/456*789/123
=123*456/789*1/456*789/123
=123*456/*789/123*456*789
=1
