1.(-5)除(-10)X(-2) 2.(-36又4分之3)除(-9)
(-5)÷(-10)x(-2)
=(-5)x(-2)÷(-10)
=10÷(-10)
=-1
(-36又3/4)÷(-9)
=(-36-3/4)÷(-9)
=36÷9+3/4÷9
=4+1/12
=4又12分之1

如果本题有什么不明白可以追问,

(-5)除(-10)X(-2)
=0.5*(-2)
=-1
(-36又4分之3)除(-9)
=147/4*(1/9)
=4又1/12

1. -5/(-10)*(-2)=-1
2. (-36-3/4)/(-9)=147/36=4又1/12

1、(-5)除(-10)X(-2)
=0.5×(-2)
=-1
2、(-36又4分之3)除(-9)
=-147/4 ×(-1/9)
=49/12
=4又1/12
