Números Racionales


6. (3/4)+(5/9)= (3/4) + 5/9 15/36


7. (6/2)-14/4)= (6/2) - 14/4 = - 84/12


8. (3/5)(12/3) - (4/7)(6/11)= 36/15 = 24/77 = -60/92


9. (((4/3)(6/2)/(4/4)))+(2/5) + 3/4 - 16/7=...


10. (18/5)(9/2) + 25/3 - 6/4 - 7/15 = ...



11. (14/3)/(23/11) + 9/6(5/4)= 154/12 + 36/30 = 42/184 = 21 /92



12. (((5/25)(16/2)/(25/7)(13/6))/(12/7) + 3/2 = ...
