解:17.4X4.5+5.5+17.5
=17.4X4.5+17.4+0.1+5.5
=17.4(4.5+1)+5.5+0.1
=17.4X5.5+5.5+0.1
=5.5X18.4+0.1
=101.3
=17.4X4.5+17.4+0.1+5.5
=17.4(4.5+1)+5.5+0.1
=17.4X5.5+5.5+0.1
=5.5X18.4+0.1
=101.3

17.4×4.5+5.5+17.5
=17.4×4.5+5.5+17.4+0.1
=17.4×(4.5+1)+5.5+0.1
=17.4×5.5+5.5+0.1
=5.5×(17.4+1)+0.1
=5.5×18.4+0.1
=5×18.4+0.5×18.4+0.1
=92+9.2+0.1
=101.3
=17.4×4.5+5.5+17.4+0.1
=17.4×(4.5+1)+5.5+0.1
=17.4×5.5+5.5+0.1
=5.5×(17.4+1)+0.1
=5.5×18.4+0.1
=5×18.4+0.5×18.4+0.1
=92+9.2+0.1
