我不懂为什么到第二个算式是(-32-16/25)÷(-32)+2.5+1/2×24+2/3×24-3/4×24-11/12×24

追答

你看你，还说我题目没错
这样分开算比较好算，

Answer 2

(-32 16/25)÷(-8×4)÷2.5+(1/2+2/3-3/4-11/12)×24
=(1+1/50)÷2.5+(-1/2)x24
=51/20-12
=-189/20

(-32 16/25)÷(-8×4)
=(-32-16/25)÷(-32)
=(-32)÷(-32)+(-16/25)÷(-32)
=1+1/50

=(1+1/50)÷2.5
=(51/50)x(2/5)
=51/125

(-32 16/25)÷(-8×4)÷2.5+(1/2+2/3-3/4-11/12)×24
=(1+1/50)÷2.5+(-1/2)x24
=51/125-12
=-1449/125
=-11.592
