(0.8×19.85×0.125+0.075×0.125÷0.625)×100-37.5×0.4
(0.8×19.85×0.125+0.075×0.125÷0.625)×100-37.5×0.4
(0.8×19.85×0.125+0.075×0.125÷0.625)×100-37.5×0.4
(0.8×19.85×0.125+0.075×0.125÷0.625)×100-37.5×0.4
=0.8×19.85×0.125×100+0.075×0.125÷0.625×100-37.5×0.4
=8×19.85×1.25+7.5×0.125÷(5/8)-37.5×0.4
=10×19.85+7.5×0.125×1.6-37.5×4×0.1
=198.5+(7.5×4)×(0.125×0.4)-150×0.1
=198.5+30×0.05-15
=198.5+15-15
=198.5
