Question

19.4乘以0.3+194×0.06+1.94怎样简便计算？

Answer 1

19.4×0.3+194×0.06+1.94
=1.94×3+1.94×6+1.94
=1.94×10
=19.4

Answer 2

根据题目列式：
19.4x0.3+194x0.06+1.94
=19.4x0.3+19.4x0.6+19.4x0.1
=19.4x(0.3+0.6+0.1)
=19.4x1
=19.4

Answer 3

1、观察有3个加号
2、相同数字（无），相似数字有194
3、制造相同的数字，以便处理。比如194
19.4*10/10*0.3+194*0.06+1.94*100/100
194/10*0.3+194*0.06+194/100
194*0.03+194*0.06+194*0.01
然后一个一个算出来，或者用其它合理的方式算出来，得到1.94

Answer 4

=19.4*0.3+19.4*0.6+19.4*0.4
=19.4*（0.3+0.6+0.1）
=19.4*1
=19.4

Answer 5

19.4×0.3+194×0.06+1.94
=194×0.03+194×0.06+194×0.01
=194×(0.03+0.06+0.01)
=194×0.1
=19.4
