一道数学计算题~~~~~过程答案，写清楚内！

不会打上来，就照上来了咯！

Answer 1

(3.875×1/5+38又3/4×0.09-15.5÷40)/[18.25×11又4/5-17又1/4÷（1-54/59）]
=(3.875×0.2+38.75×0.09-0.3875)/(18.25×11.8-17.25×11.8）
=3.875×（0.2+0.9-0.1）/[(18.25-17.25)×11.8]
=3.875/11.8
=31/8×10/118
=155/472

Answer 2

=(3.875*0.2+3.875*0.9-3.875*0.1)/(18.25*11.8-17.25*11.8)
=3.875/[(18.25-17.25)*11.8]
=3.875/11.8
=155/472
