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

6.7乘(10加0.1) =6.7乘10+6.7乘0.1 =67+0.67=67.67

67.67

g

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

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

6点七乘10点1 =6.7×(10+0.1) =6.7×10+6.7×0.1 =67+0.67 =67.67

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

简便运算: 86×6.7-67.1 =86×6.7-67-0.1 =86×6.7-6.7×10-0.1 =6.7×(86-10)-0.1 =6.7×76-0.1 =509.2-0.1 =509.1 答题不易,望采纳~~
