3/4*1/5+3/4*2/5+0.75*3/5-3/4简便运算
3/4*1/5+3/4*2/5+0.75*3/5-3/4简便运算
3/4*1/5+3/4*2/5+0.75*3/5-3/4简便运算
3/4*1/5+3/4*2/5+0.75*3/5-3/4
=3/4*(1/5+2/5+3/5-1)
=3/4*(1/5)
=3/20
3/4(1/5+2/5+3/5-1)
=3/4*1/5
=3/20
3/4*1/5+3/4*2/5+0.75*3/5-3/4简便运算
4/3*5/1+4/3*5/2+0.75*5/3-4/3简便计算
0.75*4+0.75*5+3/4=
-5-[-4+(1-0.25*4/3#1/3)#(-0.75)]
简便算:1.95*0.75+2又1/4*3/4-1/5除以1-1/3
0.75*5/2+4/3*5/3的简便算法0.75*5/2+4/3*5/3简便,
4分之3+4分之3×5分之2+0.75×5分之3-4分之3
0.75+(-2 3/4)+(0.125)+(-12 5/7)+(-4
0.75+(-2 3/4)+10.125+(-12 5/17)+(- 4
5/9*0.75+3/4*4/9
(-3/4)+33/8+|-0.75|+(-5 1 /2)+|-2 5 /8|=?
-2^3*-(-1)^5*(-2)^4=?0.25*(-2.15)+0.75*(+3.15)/3=?一定要对
0.75+(-2又3/4)+(+0.125)+(-12又5/7)+(-4又1/8)
简便运算:1/3*4.5/(0.75+5/4)
|-0.75|+(+3又1/4)-(-0.125)-|-0.25|+(+5/8)
(0.75+3/4*99)除以1/5
3/4乘2/9+0.75乘5/9等于
0.75:3分之1 7分之4:3 1.25:4分之3 1又5分之2:0.8 求比值
