0.75*4+0.75*5+3/4=

0.75*4+0.75*5+3/4= 5/9*0.75+3/4*4/9 0.8:3又4分之3=(5-X):0.75 1/4*0.75= 3.61*0.75+0.61*3/4+(-0.2)*0.75 0.8：15/4=[5-x]：0.75 巧算3/17*3/4+36/17*0.75-0.75+12/17除以4/3=? 因为4/3×0.75=1,所以4/3的倒数是0.75. 4/3乘0.75=1所以0.75是4/3倒数,这说法对吗? -5-[-4+(1-0.25*4/3#1/3)#(-0.75)] 0.75*8/9/3/4 4分之3除以0.75 0.75=4分之几 (-3又5分之4)+4分之1+(-5分之1)+0.75= 0.75+(-2 3/4)+(0.125)+(-12 5/7)+(-4 0.75+(-2 3/4)+10.125+(-12 5/17)+(- 4 x:0.75=5分之4÷15分之4 0.75*5/2+4/3*5/3的简便算法0.75*5/2+4/3*5/3简便,
