脱式计算,能简算的要简算:4.67%(2.98+0.67); ...

(1)4.67-(2.98+0.67)=4.67-2.98-0.67=4.76-0.76-2.98=4-2.98=1.02(2)73.8×16-73.8×6=73.8×(16-6)=73.8×10=738(3)(45+14)÷73+710=2120×37+710=920+1420=2320

4.67-(2.98+0.67) =4.67-0.67-2.98 =4-2.98 =4-(3-0.02) =4-3+0.02 =1.02 1110÷(56×(7分之3-8分之3)) =1110÷(56×3/7-56×3/8) =1110÷(24-21) =1110÷3 =370 9分之8×(7分之3÷(3分之2+7分之1)) =8/9×(3/7×21/17) =8/9×9/17 =8/17 ...

二、计算(能简算的要简算) 4.67-(2.98+0.67) 73.8×16-73.8×6 (...使我对辩证的思想有了新的认识,以至于我在许多的征文比赛中脱颖而出,摘得桂冠...

4.67-(2.98+0.67)=4.67-0.67-2.98 =4-3+0.02 =1.02
