1/27+505/2727+131313/272727+35353535/27272727(请写出运算过程)
39*148/149+148*86/149+48*74/149(同上)
39*148/149+148*86/149+48*74/149(同上)
看上去很复杂,其实想想也很简单...
具体步骤如下:
鼠标左键依次点击开始-所有程序-附件-计数器.
然后在计数器中输入1/27+505/2727+131313/272727+35353535/27272727:
39*148/149+148*86/149+48*74/149(如果嫌点鼠标太麻烦可以用键盘直接输入数字)
再嘛就....
1/27+505/2727+131313/272727+35353535/27272727
=1/27+5/27+13/27+35/27
=(1+5+13+35)/27
=63/27
=7/3
1/27+505/2727+131313/272727+35353535/27272727
=1/27+5/27+13/27+35/27
=(1+5+13+35)/27
=63/27
=7/3
=1/27+101*5/101*27+10101*13/10101*27+1010101*35/1010101*27
=1/27+5/27+13/27+35/27
=54/27
=2
=(39+86)*148/149+24*148/149
=149*148/149
=148
1/27+505/2727+131313/272727+35353535/27272727
=1/27+5/27+13/27+35/27
=(1+5+13+35)/27
=63/27
=7/3
