Question

Выполните деление 3/14:(-2/21)=: -12:(-6/7)=; -3/4:(-5)=; -1 8/27:(1 5/9)= ; -3 3/26:(-2 10/13)

Answer 1

3/14:(-2/21)=3/14*(-21/2)=-9/4=-2 1/4
-------------
-12:(-6/7)=-12*(-7/6)=14
--------------
-3/4:(-5)=-3/4*(-1/5)=3/20
-------------
-1 8/27:(1 5/9)= -35/27:14/9=-35/27*9/14=-5/6
---------------
-3 3/26:(-2 10/13)=-81/26:(-36/13)=-81/26*(-13/36)=9/8=1 1/8
