问题描述:
100乘以101分之2等于多少
答
100乘以101分之2
=(101-1)x2/101
=101x2/101-1/101
=2-1/101
=1又100/101
答
哪里用的了那么麻烦,用约的,得2.
答
(101-1)*2/101
=2-2/101
=1又99/101
答
=(101-1)×101分之2
=101×101分之2-1×101分之2
=2-×101分之2
=1又×101分之99
答
100x2/101
=(101-1)x2/101
=2-2/101
=1又99/101
答
100*(2/101)=(100+1)*(2/101)-1*(2/101)=2-(2/101)=1又(2/101)
