11.2除以9.6乘以2.4如何简便运算

11.2÷9.6x2.4 解:简便计算 =11.2÷2.4÷4x2.4 =11.2÷4 =2.8 祝天天向上。

2.22×9.9+6.66×6.7 =2.22×3×3.3+6.66×6.7 =6.66×(3.3+6.7) =6.66×10 =66.6

6.28x0.9=6.28x(1-0.1) =6.28-0.628 =5.652 3.14x11=3.14x(10+1) =31.4+3.14 =34.54 9.42x2.4=9.42x(2+0.4) =18.84+3.768 =22.608

=【(3.2×2)×(1.11×3)×(1.6×6)】÷【(1.6×1)×(3.2×1)×(1.11×10)】 =【(3.2×1.6×1.11)×(2×3×6)】÷【(3.2×1.6×1.11)×(1×1×10)】 =(2×3×6)÷(1×1×10) =36÷10 =3.6

因为此数加3以后,能被7,9整除,除以11余57×9=63,63÷11=5….8,8×2=16,除以11余5,最小可能是:63×2-3=123.故答案为:123.

5/9+11/9-(5/6-2/9) =16/9-(5/6-2/9) =(16/9+2/9)-5/6 =2-5/6 =1又1/6

1.125*3+125*5+25*3+25 2.9999*3+101*11*(101-92) 3.(23/4-3/4)*(3*6+2) 4. 3/7 × 49/9 - 4/3 5. 8/9 × 15/36 + 1/27 6. 12× 5/6 – 2/9 ×3 7. 8× 5/4 + 1/4 8. 6÷ 3/8 – 3/8 ÷6 9. 4/7 × 5/9 + 3/7 × 5/9 10. 5/2 -( 3/2 + 4/5 ) 11. 7/8 + (...

18分之11×9-11分之8×6 =2分之11-11分之48 =22分之121-22分之96 =22分之25 结果是22分之25

99.9X6+22.2X23 =11.1X(9X6)+11.1X(2X23) =11.1X(54+46) =11.1X100 =1110

1.125*3+125*5+25*3+25 2.9999*3+101*11*(101-92) 3.(23/4-3/4)*(3*6+2) 4. 3/7 × 49/9 - 4/3 5. 8/9 × 15/36 + 1/27 6. 12× 5/6 – 2/9 ×3 7. 8× 5/4 + 1/4 8. 6÷ 3/8 – 3/8 ÷6 9. 4/7 × 5/9 + 3/7 × 5/9 10. 5/2 -( 3/2 + 4/5 ) 11. 7/8 + (...
