16-6*0.54+1.66*3.6+1.66=16-6*0.54+1.66*（3.6+1）=20.396
(4.85÷18分之5-3.6+6.15×3又5分之3)×(1-9分之8)=(4.85×18/5-3.6+6.15×18/5)×(1/9)=(0.97×18-3.6+1.03×18)×(1/9)=(2
（3+0.6）（6-0.2）+（11-0.2）（1+0.4）=18-0.6+3.6-0.12+11+4.4-0.2-0.08=36
7.9*0.64+0.79*3.6=7.9*0.64+7.9*0.36=7.9*(0.64+0.36)=7.9*1=7.9
3.6*8.4+3.6*2*0.8=3.6*8.4+3.6*1.6=3.6*(8.4+1.6)
6.4*4.5+3.6*45=0.64*45+3.6*45=45*(0.64+3.6)=45*4.24=190.8
(9/2)*3.6+(26/5)*0.35=17.2
=1.11×8×0.8+1.11×3.6=1.11×6.4+1.11×3.6=1.11×(6.4+3.6)=1.11×10=11.1
3.35*6.4*2+6.7*3.6=(3.35*2)*6.4+6.7*3.6=6.7*6.4+6.7*3.6=(6.4+3.6)*6.7=10*6.7=67【么么、应该是这样吧、有点长哦、呵呵】
3.6-3.6×0.5=3.6×(1-0.5)=3.6×0.5=1.8
1.25×39.8×0.8=1.25×0.8×39.8=1×39.8=39.83.6×0.7×2.5=0.9×4×0.7×2.5=4×2.5×0.9×0.7=10×0.63=6.3
1.8*19.2-3.6*4.6=1.8*19.2-1.8*2*4.6=1.8*(19.2-2*4.6)=1.8*10=18
2.8*3.6+2.8=2.8*(3.6+1)=2.8*(5-0.4)=2.8*5-2.8*0.4=14-1.12=12.88
25/8*7.4-25/8+3.6*3.125=25/8*(7.4-1+3.6)=3.125*10=31.25
3.6*3.6+1.4*3.6=3.6*（3.6+1.4）=3.6*5=180.25*0.8*0.125*0.4=（0.25*0.4）*（0.8*0.125）=0.1*0.1=0.012.7*1.5-
4.28*（3.6+6.1）+9.7*5.724.28*9.7+9.7*5.729.7*（4.28+5.72）9.7*1097
=(33*35+34*35+35*36+35*37-33+37)/100=(4*35*35+4)/100=4904/100=49.04
等于36.28.
原式=4.7×2×1.4+3.6×9.4=9.4×1.4+3.6×9.4=9.4×（1.4+3.6）=47
