17.1×0.51+8.29×5.1
= 17.1×(1)x0.51+8.29×5.1
= 17.1x(0.1x10)x0.51+8.29×5.1
= (17.1x0.1)x(10x0.51)+8.29×5.1
= 1.71x5.1+8.29×5.1
= 5.1x(1.71+8.29)
=5.1x10
=51
= 17.1×(1)x0.51+8.29×5.1
= 17.1x(0.1x10)x0.51+8.29×5.1
= (17.1x0.1)x(10x0.51)+8.29×5.1
= 1.71x5.1+8.29×5.1
= 5.1x(1.71+8.29)
=5.1x10
=51

17.1×0.51+8.29×5.1
=17.1×0.51+82.9×0.51
=(17.1+82.9)×0.51
=100×0.51
=51
=17.1×0.51+82.9×0.51
=(17.1+82.9)×0.51
=100×0.51
=51

解:原式=1.71ⅹ5.1+8.29ⅹ5.1
=5.1(1.71+8.29)
=5.1x10
=51
=5.1(1.71+8.29)
=5.1x10
=51

5.1等于0.51*10
17.1*0.51+8.29*0.51*10=17.1*0.51+82.9*0.51=0.51*(17.1+82.9)=0.51*100=51
17.1*0.51+8.29*0.51*10=17.1*0.51+82.9*0.51=0.51*(17.1+82.9)=0.51*100=51
