(10/3×1.9+19.5÷9/2)/(62/75-0.16)÷（3.5+14/3+32/15)/[0.5×（21/20+4.1)
问题描述：
(10/3×1.9+19.5÷9/2)/(62/75-0.16)÷（3.5+14/3+32/15)/[0.5×（21/20+4.1)
答
(10/3×1.9+19.5÷9/2)/(62/75-0.16)÷（3.5+14/3+32/15)/[0.5×（21/20+4.1)=(10/3×19/10+39/2×2/9)/(62/75-12/75)÷（105/30+140/30+64/30)/[0.5×（21/20+82/20)=(19/3+13/3)/(50/75)÷(309/30)/(103/40)=32/3...
