0.75*24/0.25= 0.75*24*0.25= 16+4/2.5= 0.51/1.7+0.35*0.2= 8.9*1.7-5.13= 0.36+1.6/2.5= 7.8*7.5/2.6*4= 10.4/(5.28/4.4+1.4)=
0.75 X 24 / 0.25
= 24 X 0.75 / 0.25
= 8 X 3 X 3
= 72
0.75 X 24 X 0.25
= 3/4 X 4 X 6 X 1/4
= 3 X 3 / 2
= 4.5
16 + 4/2.5
= 16 + 16/10
= 17.6
0.51 / 1.7 + 0.35 X 0.2
= 0.3 + 0.7 X 0.1
= 0.37
8.9 X 1.7 - 5.13
= 10 X 1.7 - 1.1 X 1.7 - 5.13
= 17 - 1.87 - 5.13
= 17 - 7
= 10
0.36 + 1.6 / 2.5
= 0.36 + 6.4 / 10
= 0.36 + 0.64
= 1
7.8 X 7.5 / 2.6 X 4
= 4 X 7.5 X 78 / 26
= 30 X 3
= 90
10.4 / ( 5.28 / 4.4 + 1.4 )
= 10.4 / ( 13.2 / 11 + 1.4 )
= 10.4 / ( 1.2 + 1.4 )
= 104 / 26

0.75*24+0.75/0.25的简便算法.
5-0.25+0.75 = =
x^2-4(0.5-0.25x)(1.5-0.75X)-24(0.5-0.25X)^2 忘了,最后=0
×+1分之0.75=0.25
(-0.75)除以0.25=?
多元线性回归分析x1=[2 2 2 2 2 2 5 5 5 5 5 5 7 7 7 7 7 7 10 10 10 10 10 10];x2=[0 0 0 1 1 1 0 0 0 1 1 1 0 0 0 1 1 1 0 0 0 1 1 1];x3=[0.25 0.50 0.75 0.25 0.50 0.75 0.25 0.50 0.75 0.25 0.50 0.75 0.25 0.50 0.75 0.25 0.50 0.75 0.25 0.50 0.75 0.25
计算 0.25*(-2.15)+0.75*(+3.15)/3=?
8/9*[0.75-(5/16+0.25)]=
0.64*0.25+0.75= 的简便方法
1-0.75x=0.25 解方程
5.4-0.25=0.75的简便,
简便计算:8×[0.75-0.25×(4-2)]
化简 3分之2:0.25 0.75:1
0.75>0.25x-2怎么算
简便:(1)18÷0.75×0.75 (2)12.5×0.7×0.8 (3)0.25×4.35-0.25×0.35 = = = = = = = = =
x-0.25-0.75=y+0.25解方程
判断题:因为0.25+0.75=1,所以0.25和0.75互为倒数()
( ):24=( )/( )=0.75=15:( )=( )%
