解答
(0.7*2/3-0.11*5/6)/0.625-0.03=(1.4/3-0.55/6)/0.625-0.03=(2.25/6)/0.625-0.03=0.6-0.03=0.57
推荐
11分之3*()=1.5*()=1又5分之2*()=0.625*()=7又2分之1/()=1
巧算:2.2*0.4*1.25*2.6 1.625+2.625+3.625+…+80.625 5.5*6.6+6.6*7.7+7.7*8.8+8.8*9.9
8又5分之4÷[7.8+0.625×(4分之11-1.15)]
8/5×5.3+5.7×8/5-0.625
直接写得数. 3/8+0.625= 1÷0.05= 9.7+0.03= 4/5×5/28= 78×9.9+7.8= 12-27/9= 10÷10%= 1-1/4-1/3= 613/17-3/4-4.25= 3/7+5/21-3/7+10/2
