如题所述
(4.5÷0.15-4.5)÷0.25
=(4.5÷3/20-4.5)÷1/4
=(4.5*20/3-4.5)*4 除以一个数等于剩以它的倒数
=[4.5*(20/3-1]*4
=9/2*17/3*4
=51/2*4
=51*2
=102
=(4.5÷3/20-4.5)÷1/4
=(4.5*20/3-4.5)*4 除以一个数等于剩以它的倒数
=[4.5*(20/3-1]*4
=9/2*17/3*4
=51/2*4
=51*2
=102

原式=4.5÷0.15÷1/4-4.5÷1/4
=4.5×4÷0.15-4.5×4
=18÷0.15-18
=120-18
=102
=4.5×4÷0.15-4.5×4
=18÷0.15-18
=120-18
=102
