简便运算:20.7-6.32-0.68 9.25*0.8+9.25*0.2 0.89*100.1 24*(3/8+5/6) 24/13-(1/5+11/13)-4/51.7*3.5-3.5*1.5 6*1/4+14/4 23.19+2.4+2.91+14.6 7.32*4.8+0.52*73.2 7/9/11/5+5/11*2/9 25/17-1/3*9/8-5/8 3/4*3/8+(1-5/8)*1/4 16
20.7-6.32-0.68=20.7-(6.32+0.68)=20.7-7=13.7
9.25*0.8+9.25*0.2=9.25*(0.8+0.2)=9.25*1=9.25
0.89*100.1=0.89*(100+0.1)=0.89*100+0.89*0.1=89+0.089=89.089
24*(3/8+5/6)=24*3/8+24*5/6=9+20=29
24/13-(1/5+11/13)-4/5=24/13-11/13-(1/5+4/5)=13/13-5/5=1-1=0

你往度娘上度娘一下就知道了

20.7-(6.32+0.68) (0.8+0.2)×9.25 0.89×100+0.89×0.1 24×(3/8+5/6)(直接算)
