Răspuns :
a) 27/14 -0 = 27/14
b) 2/3 -(5/10 - 1/2 ) = 2/3 - 0 = 2/3
c) 34 /5 - ( 23/2-69/6) = 34/5 - 0 = 34/5
b) 2/3 -(5/10 - 1/2 ) = 2/3 - 0 = 2/3
c) 34 /5 - ( 23/2-69/6) = 34/5 - 0 = 34/5
a)scăzându se 0
rezultatul e 27/14
b)2/3-(1/2-1/2)=2/3
5/10 simplif prin 5 este 1/2
c)34/5-(23/2-69/6)=
34/5-(23/2-23/2)=
34/5
69/6=23/2
rezultatul e 27/14
b)2/3-(1/2-1/2)=2/3
5/10 simplif prin 5 este 1/2
