Question

ex 2 efectueaza 8supra10-(5supra10+2supra10= 15supra17-(13supra17-6supra17)= ( 9supra27+23supra27)-12supra27 (45supra60-27supra60)+(35supra60-7 supra60)

Answer 1

8/10-(5/10+2/10)=
8/10-7/10=1/10

15/17-(13/17-6/17)=
15/17-7/17=8/17

(9/27+23/27)-12/27=
32/27-12/27=20/27

(45/60-27/60)+(35/60-7/60)=
18/60+28/60=46/60

Answer 2

8/10-(5/10+2/10)=
8/10-7/10=1/10 15/17-(13/17-6/17) 15/17-7/17= 8/17 (9/27+23/27)-12/27 32/27-12/27=20/27
