21/7除以6/5乘以22/9除以11/9=3*5/6*22/9*9/11=6又5/6。

=2/9*33*6/11 =2/9*18 =2*2 =4

66X9+11+46 =11x6x9+11+44+2 =11x(54+1+4)+2 =11x59+2 =(10+1)x59+2 =590+59+2 =590+61 =651 另一种 66X9+11+46 =66x9+57 =66x9+66-9 =66x(9+1)-9 =66x10-9 =660-9 =651

=【(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

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 + (...

99.9×6+22.2×23 =11.1×9×6+11.1×2×23 =11.1×54+11.1×46 =11.1×(54+46) =11.1×100 =1110

9╱11+5╱6+2╱11-1╱6 =9╱11+2╱11+5╱6-1╱6 =1+2╱3=5╱3
