2.1 3.5 0.4简便运算

2.1/3.5/0.4的简便运算2.1÷3.5÷0.4 =2.1÷(3.5x0.4)=2.1÷1.4=1.5 希望能帮到你

2.1÷3.5÷0.4=0.6÷0.4=1.5

能2.1÷3.5÷0.4=0.3*7÷7÷(0.5*0.4)=0.3÷0.2=1.5

3.5*2.4+2.1*0.4可拆分成=3.5*2+3.5*0.4+2.1*0.4=7+5.6*0.4=7+2.24=9.24

2.1*3.5+2.1*2.5用简便的方法计算=2.1x(3.5+2.5)=2.1x6=12.6

3.5*(2.4-0.4)=3.5*2=7

2.1除以2.5再除以0.4脱式简便运算2.1÷2.5÷0.4 =2.1÷(2.5x0.4)=2.1÷1=2.1

0.15+(3.74-1.8)/0.4 =(0.06+3.74-1.8)/0.4 =(3.8-1.8)*5/2 =2*5/2 =5

3.5*0.4-2.4*0.3=3.50.4-0.46x0.3=0.4x(3.5-1.8)=0.4x1.7=0.68

展开全部2.5/(3.5-2.7)*0.4=1/0.8=1. 25
