Urgent!!!!!! Va roooog!!!!!Ofer 50 de puncte

Answer 1

-9/12+10/12=1/12

5/8-16/8=-11/8

+45/90=1/2


14/6-7/3=0


(2/3)* (-1/12 )=-2/36=-1/18


-5/3+3/3=-2/3


5/8-6/8=-1/8


2*(-4)=-8





- (9*7*8*8)/(8*5*9*3)= -(7*8/5*3)=-56/15



(-2/5) *(3/1)=-6/5





-0,4*10/1=-4
 


daca este
-2\5:1-/10  cum ai scris,   acel ' - ' nu are ce cauta acolo; dac este 1/(-10) sau -(1/10) atunci rezultatuleste =4
