嗯1.25乘以四点二除以括号零点七除以八括号

1.25*4.2÷(0.7÷8)=1.25*4.2÷0.7*8=1.25*8*(4.2÷0.7)=10*6=60

1.25*(0.8*5.7+7.2*5.7)=1.25*(0.8+7.2)*5.7=1.25*8*5.7=10*5.7=57

1.25*4.2÷(0.6÷8)=(1.25*8)*(4.2÷0.6)=10*7=70

1.25乘零点5+4点七五除以二简便算法1.25乘零点5+4点七五除以二=0.5*(1.25+4.75)=0.5*6=3

1÷2*3÷(2÷6)*(5÷3÷2)*7÷1.4=1/2*3÷1/3*5/6*7÷1.4=1/2*3*3*5/6*5=1/2*25/6=25/12=2又1/12

3又2/7X1.25十4又5/7除以0.8=1.25x(3又2/7十4又5/7)=1.25X8=10

10÷0.2÷2.5=50÷2.5=20望采纳,谢谢
