6.5乘2.3加6.5乘6.7加6.5用脱式计算

6.5X2.3+6.7X6.5 =6.5X(2.3+6.7) =6.5X9 =58.5

3.8×6.7+3.8×3.3 =3.8×(6.7+3.3) =3.8×10 =38

2/3+5/6+1/7脱式计算 =28/42+35/42+6/42 =69/42 =1又27/42

7.2*6.9=49.6849.68*6.7=332.856

3/7*1/6+3/7*5/6 (运用乘法分配律 a*(b+c)=a*b+a*c) =3/7...

(7/8-3/16)×(5/6+2/3) =11/16×3/2 =33/32

脱式计算5.25x6.7+4.75x6.7怎么计算 5.25x6.7+4.75x6.7 =6.7...

=(3.5+6.5)+1.7×1.7 =10+2.89 =12.89 你好,本题已解答,如果满意,请...

5/6-7/12+3/4 =20/24-14/24+18/24 =24/24 =1
