回答1:

3.6*11.1+1.2*66.7=1.2*3*11.1+1.2*66.7=1.2*33.3+1.2*66.7=1.2*(33.3+66.7)=1.2*100=120

回答2:

=1.2*3*11.1+1.2*66.7
=1.2*33.3+1.2*66.7
=1.2*(33.3+66.7)
=1.2*100=120

回答3:

3.6*11.1+1.2*66.7=3.6*11.1+1.2*(100-33.3)=3.6*11.1+1.2*100-1.2*11.1*3=1.2*100=120

回答4:

3.6×11.1+66.7×1.2=(1.2×3)×11.1+66.7×1.2=1.2×(3×11.1+66.7)=1.2×100=120
