-1+5÷(-6分之1)×(-6)

问题描述:

-1+5÷(-6分之1)×(-6)
(-10又8分之1)÷2又4分之1×9分之4÷(-2)
-6又4分之1+8又4分之1÷(-2又12分之7×31分之3)
(-5)÷(-1又7分之2)×5分之4×(-2又4分之1)÷7
(-27)÷4分之9×9分之4÷(-24)
(-1)×[4又3分之2÷(-4)-(-1又4分之1)×(-0.4)÷(-3分之1)]

-1+5÷(-6分之1)×(-6)=-1+5*(-6)*(-6)=179
(-10又8分之1)÷2又4分之1×9分之4÷(-2)
-6又4分之1+8又4分之1÷(-2又12分之7×31分之3)
=-25/6+33/8/((-31/12)*(3/31))
=-25/6+33/8/(-1/4)
=-25/6+(-33/2)
=(-25-33*3)/6
=-62/3
(-5)÷(-1又7分之2)×5分之4×(-2又4分之1)÷7
=5/(9/7)*(4/5)*(-9/4)/7
=5*(7/9)*(4/5)*(-9/4)*(1/7)
=-1
(-27)÷4分之9×9分之4÷(-24)
=-27*(-4/9)*(4/9)*(-1/24)
=-2/9
(-1)×[4又3分之2÷(-4)-(-1又4分之1)×(-0.4)÷(-3分之1)]
=-1*[(14/3)*(-1/4)-(-5/4)*(-4/10)*(-3)]
=-1*[-7/6+3/2]
=-1/3
