16-6*0.54+1.66*3.6+1.66=16-6*0.54+1.66*（3.6+1）=20.396
3.6x+3.6(x-15)=4863.6x+3.6x-54=4867.2x=486+547.2x=540x=540÷7.2x=75
26.4*3.6-3.6*16.4＝3.6×﹙26.4－16.4﹚＝3.6×10＝36.
3.6x42.3x3.75-12.5x0.423x16=36x0.423x37.5-12.5x0.423x16=4x9x0.423x12.5x3-12.5x0.423x4x4=4x12.5x0.423
前者是-3.6,后者是-3.6.你说呢?肯定是等于啊.
26.4×3.6-0.36×164怎样简便计算·=0.36×（264-164）=0.36×100=36；很高兴为您解答,skyhunter002为您答疑解惑如果本题有什么不明白可以追问,
X分之0.4=16分之3.60.4/x=3.6/163.6x=16×0.43.6x=6.4x=6.4/3.6x=16/9再问：谢谢啊
3.6x+3.6x-15=4683.6+3.6=468+157.2x=483x=483除以7.2x=67.083333333333333333333333333333333333.
（26.4-16.4)×3.6
第二项分子分母3.6先约掉,变成3.6+(3.6-3.6/3.6)=3.6+3.6-1=6.2
26.4x+18x=66.644.4x=66.6x=66.6÷44.4x=1.50.5×6+3x=4.83+3x=4.83x=4.8-33x=1.8x=1.8÷3x=0.62.5x-6=18.52.5
原式=3.6（1-0.8）=3.6*0.2=0.72
3.6-3.6×0.5=3.6×(1-0.5)=3.6×0.5=1.8
3.6*0.75/3.6*0.75=3.6/3.6*0.75*0.75=3/4*3/4=9/16
亲,我来给你解答吧~(X+3.6)*5/2=16(x+3.6)*5=32x+3.6=32/5x+3.6=6.4x=6.4-3.6x=2.8新年快乐哦亲,
100天哦再问：具体列式再答：再问：再问：帮我看看那个有图的题
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-
