Question

0.34 0.34x7.3 3.7x0.34简便方法计算

Answer 1

0.34不用算吧，就是一个数字
0.34*7.3=0.34*7+0.34*0.3=2.38+0.102=2.482
3.7*0.34=0.001*（37*34）=0.001*（37*30+37*4）=0.001*（1258）=1.258
我估计是楼主漏了加号，原题应该是：0.34+0.34x7.3+0.34x3.7=0.34x（1+7.3+3.7）=0.34*12=0.34*10+0.34*2=3.4+0.68=4.08

Answer 2

简便方法计算
0.34+0.34x7.3+3.7x0.34
=0.34×（1+7.3+3.7）
=0.34×12
=4.08

Answer 3

0.34+0.34×7.3+3.7×0.34
=0.34×(1+7.3+3.7)
=0.34×12
=0.34×(10+2)
=0.34×10+0.34×2
=3.4+0.68
=4.08

Answer 4

0.34×7.3 +3.7 ×0.34-0.34
=0.34×（7.3+3.7-1）
=0.34×10
=3.4
