-4/9÷(-2/3)=

-4/9 × (-3/2)=2/3

2/3÷(-5/9):(10/3)=

2/3×(-9/5):10/3=

-6/5 × 3/10= -18/50= -9/25

(1/4÷5)÷(5÷50/3)=

(1/4×1/5):(5×3/50)=

1/20:3/10=

1/20×10/3=2/3
-4/9(impartit) (-2/3)= 4/9 x3/2= 2/3
2/3(impartit) (-5/9) (impartit) (10/3)= -2/3x9/5x3/10 = -9/5x 1/5 = -9/25
(1/4 impartit 5) impartit (5 impartit 50/3)= (1/4x1/5) impartit (5x 3/50)= 1/20 impartit 3/10= 1/20x10/3=1/2x1/3=1/6
