0.72 3.6的简便计算

原式=0.36*(2.8+7.2)=3.6希望能帮到你,请采纳正确答案.你的点赞或采纳是我继续帮助其他人的动力

12.9/0.72+43.5/3.6=129/7.2+43.5/3.6=64.5/3.6+43.5/3.6=108/3.6=30

0.72+9.8*3.6=3.6*0.2+9.8*3.6=3.6*(0.2+9.8)=3.6*10=36

解:3 .6(5.8+4.4)-0.72 =3.6*10.2-0.72 =36.72-0.72 =36解此题注意公式ab+ac=a(b+c),有相同乘数请提前

36*=36*1.1=36+3.6=39.6

3.6!

0.72*3.6+3.6*0.28=(0.72+0.28)*3.6=1*3.6=3.6

您好:2.5*0.72+3.6*0.72-0.072*11=2.5*0.72+3.6*0.72-0.72*1.1=0.72x(2.5+3.6-1.1)=0.72x5=3.6如果本题有什么不明白可以追问,如果满意请点击“采纳为满意回答”如果有其他问题请采纳本题后另发点击向我求助,答题不易,请谅解,谢谢.祝学习进步!

3.6x5.8+3.6x4.4-0.72=3.6x5.8+3.6x4.4-3.6x0.2=3.6x(5.8+4.4-0.2)=3.6x10=36

12.9/0.72+43.5/3.6 =12.9/0.72+(43.5*0.2/0.72) =(12.9+43.5*0.2)/0.72 =(12.9+8.7)/0.72 =21.6/0.72 =30
