谁能给我100道(最好是北师大版)六年级上四则混合运算的题目、过程、答案
请告诉我100道(最好是北师大版)六年级上四则混合运算的题目、过程,
题目是有加减乘除的,不要有分数,不要太简单,
加号:+
减号:-
乘号:X(就用英文字母"X"代替)
除号:·(一时间找不到好的,就用方程里的.)
格式按这个:
(我就写个简单的了,不许学我的题.)
①25X125X8X4
=(25X4)X(8X125)
=100X1000
=100000
②.
③.
尽量写整齐,不许随便写一个,不要抄别人的
只要被我选了最佳答案,最少给三十分(你还会得到系统赠送的20分.一共五十分)最高给八十分.
一定要在1月25日以前给我答案
(为了以防万一,我先给5分,等选了答案后再加)
我不希望出现像 a827181564 那样的答案,要是不尊重我,我可对你不客气!
56x75%-46x0.75 99x25%+0.25 0.88x125%
=(56-46)x0.75 =99x0.25+0.25x1 =8x0.11x125%
=10x0.75 =(99+1)x0.25 =8x1.25x0.11
=7.5 =100x0.25 =10x0.11
=25 =1.1
72%x5/24+28%x5/24 (4/7+50%)x7/25 56÷(1-3/5)
=(72%+28%)x5/24 =4/7x7/25+50%x7/25 =56÷2/5
=1x5/24 =4/25+1/2x7/25 =56x5/2
=5/24 =8/50+7/50 =28
=15/50
=3/10
哥,俺真的太累了,剩下的你自己算好不?
