12.85/0.75+2.15*4/3怎么转化?
12.85/0.75+2.15*4/3怎么转化?
12.85*4/3+2.15*4/3=4/3*(12.85+2.15)=4/3*15=20
12.85/0.75+2.15*4/3怎么转化?
计算 0.25*(-2.15)+0.75*(+3.15)/3=?
-2^3*-(-1)^5*(-2)^4=?0.25*(-2.15)+0.75*(+3.15)/3=?一定要对
题目:用简便方法计算,并说明有关理由.1. 2.15+(-4.25)+(-0.75)+(-3/题目:用简便方法计算,并说明有关理由.1. 2.15+(-4.25)+(-0.75)+(-3/20)2. (-3/4)+(-1/6)+(+1/4)+(-5/6)
2.15+(-4.25)+(-0.75)+(-二十分之三)
2.15-(5/6-1/12) 5/17-4/51+2/3是2.15
0.75*4+0.75*5+3/4=
3.61*0.75+0.61*3/4+(-0.2)*0.75
0.75*8/9/3/4
4分之3除以0.75
tan◎=0.75=37°?如何计算tan◎=3/4=0.75=37°?如何计算我想问的就是tan◎=.075 怎计算tan角度出来
简便算法 64.3*0.75+34.7*4分之3+0.75
7.5*3/4+0.75*1/2-0.75简便算
2.15的5分之3比4分之3少多少
25×0.75×(-4)×(-3分之4)
5/9*0.75+3/4*4/9
1,.7分之6的9分之7是多少 2.15里面有几个4分之3
9又8分之3-2.15+0.625-4又20分之17 等于多少
