列竖式计算3.2÷0.4÷0.25

3.2÷0.25=12.8

3.2÷0.25÷0.4=3.2÷(0.25*0.4)=3.2÷0.1=32

3除以0.25列竖式计算 12 0.25 | 30 25 50 50 0

竖式横排,4 ÷ 0.25= 400 ÷ 25= 250 ÷25 + 150 ÷ 25= 10 + 6= 16

3.2÷0.04=80 800.04|3.2 ̄ ̄ 3.2 0

=1÷(4*0.25*8*0.05*0.5) =1÷(1*0.4*0.5) =5

32÷0.25÷0.4=32÷(0.25*0.4)=32÷0.1=320

列竖式计算49.7÷0.25÷4=49.7÷(0.25x4)=49.7÷1=49.7

把3.2÷0.4转化成:32÷4

3.2÷0.4*0.25+5.6计算如下:3.2÷0.4*0.25+5.6=8*0.25+5.6=2+5.6=7.6
