计算：238÷[（98-14）÷75+12×85][3.25-3.25÷（10.3+2.2）]×0.1+5.6×2.5÷5.6×2.5．

Question

计算：
2(3)/(8)÷[（(9)/(8)-(1)/(4)）÷(7)/(5)+(1)/(2)×(8)/(5)]
[3.25-3.25÷（10.3+2.2）]×0.1+5.6×2.5÷5.6×2.5．

Answer 1

2(3)/(8)÷[（(9)/(8)-(1)/(4)）÷(7)/(5)+(1)/(2)×(8)/(5)]，
=2(3)/(8)÷[(7)/(8)÷(7)/(5)+(1)/(2)×(8)/(5)]，
=2(3)/(8)÷[（(5)/(8)+(4)/(5)]，
=2(3)/(8)÷(57)/(40)，
=1(2)/(3)；

[3.25-3.25÷（10.3+2.2）]×0.1+5.6×2.5÷5.6×2.5，
=[3.25-3.25÷12.5]×0.1+5.6×2.5÷5.6×2.5，
=[3.25-0.26]×0.1+5.6×2.5÷5.6×2.5，
=2.99×0.1+5.6×2.5÷5.6×2.5，
=0.299+6.25，
=6.549．
