67乘3.5加3.2乘35加3.5的简便算法

67×3.5+3.2×35+3.5得数多少?？
67×3.5+3.2×35+3.5 =6.7×35+3.2×35+35×0.1 =35×（6.7+3.2+0.1）35×10 =350
3.5(67*1+3.2*10+1)3.5*100=350
用简便方法计算:32×0.65+3.2×3.5?？
32×0.65+3.2×3.5 =3.2×6.5+3.2×3.5 =3.2x（6.5+3.5）3.2x10 =32 祝你学习进步🎣🐡--🐾，有不明白的可以追问😢🦩——-🐜🏵！谢谢🌤😅|🌺🐖！
原式=3.5×3.2+（70+2）×0.65 =3.5×3.2+70×0.65+2×0.65 =3.5×3.2+3.5×2×6.5+2×0.65 =3.5（3.2+13）＋1.3 =3.5×16.2+1.3 =35+21.7+1.3 =35+23 =58
五年级下册数学简便算法带答案?？
33×3.56 =8.67×3.56＋1.33×3.56 =(8.67＋1.33)×3.56 =10×3.56 =35.6 例17🥀💐_💐、15.6÷4－5.6×1/4 =15.6×1/4－5.6×1/4 =(15.6－5.6)×1/4 =10×1/4 =2又1/2 例18⚡️_——*、16/23×27＋16×19/23 =27/23×16＋16×19/23 =16×（27/23＋19/23）..
32×0.65+3.2×3.5 =32×0.65+32×0.1×3.5 =32×0.65+32×0.35 =32×（0.65+0.35）32×1 =32
32x0.65+3.2x3.5的简便方法??？
=32×0.65＋32×0.35 =32x（0.65+0.35）＝32x1 =32
原式=3.5X4.2X10-3.5X10X3.2+3.5X10=3.5X(4.2X10-3.2X10+1X10)=3.5X10X(4.2-3.2+1)=35X2=70
