4.2➗2.16➗0.18✖️17
=4.2➗2.16➗0.18✖️17
=(4.2*17)/(2.16*0.18)
=(1.4*17)/(0.72*0.18)
=(0.7*17)/(0.72*0.09)
=(7*17)/(0.72*0.9)
=119/(0.72-0.072)
=119/0.648
=119000/648
=29750/162
=14875/81
=183又52/81

4.2÷2.16÷0.18×17
=17×42×1000÷(216×18)
=17000×(42÷6)÷(216×3)
=17000×7÷648
=119×(1000÷8)÷81
=119×125/81
=81×125/81+38×125/81
=125+(40×125-2×125)/81
=125+(5000-250)/81
=125+4750/81
=125+58+52/81
=183又81分之52
