解:31.04 ÷ 3.2 + 6.4
= (31×100 + 4)/100 ÷ (3×10 + 2)/10 + (6×10 + 4)/10
= 3104/100 ÷ 32/10 + 64/10
= 3104/100 × 100/320 + 64/10
= 97/10 + 64/10
= (97+64)/10
= 161/10
= 16.1
= (31×100 + 4)/100 ÷ (3×10 + 2)/10 + (6×10 + 4)/10
= 3104/100 ÷ 32/10 + 64/10
= 3104/100 × 100/320 + 64/10
= 97/10 + 64/10
= (97+64)/10
= 161/10
= 16.1
