2.5×括号开6+9.728÷3.2等于多少

2.5*(6+9.728÷3.2)=2.5*(6+3.04)=2.5*9.04=22.6.

22.8-(6+9.728÷3.2)=22.8-(6+3.04)=22.8-9.04=13.76

2.5x(6+9.728÷3.2)=2.5x(6+3.04)=2.5x9.04=2.5x(9+0.04)=2.5x9+2.5x0.04=2.5x(10--1)+0.1=25-2.5+0.1=22.6

32.52-{6+9.728除以3.2}乘2.5=32.52-[ 6+9.728÷3.2 ]x2.5=32.52-(6+3.015)x2.5=32.52-22.5375=9.9825 怎么样 很好算吧! 给点分吧

2.5X(6十9.728÷3.2)=2.5X(6十3.04)=2.5X9.04=2.5*9+2.5*0.04=22.5+0.1=22.6

(1)2.5*(6+9.728÷3.2)=2.5*(6+3.04)=2.5*9.04=22.6 (2)45*7.3+27*4.5=45*(7.3+2.7)=45*10=450 (3)0.125*3.2*25=0.125*8*0.4*25 =(0.125*8)*(0.4*25)=1*10=10 (4)[8.3-(3.6+2.9)]÷0.72=[8.3-6.5]÷0.72=1.8÷0.72=2.5 (5)(140+0.42)÷7=140÷7+0.42÷7=20+0.06=20.06 (6)10.2*4.5=(10+0.2)*4.5=10*4.5+0.2*4.5=45+0.9=45.9

9.728÷3.2÷2.5=9.728÷(3.2*2.5)=9.728÷(0.8*4*2.5)=9.728÷(0.8*10)=9.728÷8=1.216

1.5*(6+9.728/3.2)=1.5x[6+(3.2x3.04)/3.2]=1.5x9.04=1.5x(10-1+0.04)=15-1.5+0.06=13.5+0.06=13.56

脱式计算2.5*括号6 97点28除以3-2括号等于多少2.5*(6+97.28÷3-2)=2.5*(6-2+)97.28÷3,结果不是有限小数核实算式表述

(6+9.728/3.2)*2.5=(6+3.04)*25=150+3*25+0.04*25=150+75+1=226
