6.7×10.1,的简便计算方法是什么?

6.7×10.1 =6.7×10+6.7×0.1 =67+0.67 =67.67

6.7×10.1 =6.7×(10+0.1) =6.7×10+6.7×0.1 =67+0.67 =67.67

67.67

6.7x10.1=6.7x(10+0.1)=6.7x10+6.7x0.1=67+0.67=67.67

5/6+3/10+1/6-7/10 =(5/6+1/6)+(3/10-7/10) =1-4/10 =6/10 =3/5

7/10×1/6+3/10÷6 =7/10×1/6+3/7×1/6 =(7/10+3/10)×1/6 =1×1/6 =1/6

10.1×7.6 =(10+0.1)×7.6 =10×7.6+0.1×7.6 =76+0.76 =76.76

(1-3/10÷6/7)×10/13 =(1-3/10×7/6)×10/13 =10/13-7/26 =13/26 =1/2

1+2+3+4+5+6+7+8+9+10+…+100=100×(100+1)2=50×101=5050.
