Question

gasiti perechile de numere egale:
3/4, -21/24, -0,75, 1,(3), 0,75, 7/8, 4/3, 0,875, 7/8, 6/8

Answer 1

3/4=3/4;
-21/24=-7/8{am simplificat prin 3};
-0,75=-3/4;
1,(3)=(13-1)/9=12/9=4/3{am simplificat prin 3};
0,75=3/4;
7/8=7/8;
4/3=4/3;
0,875=875/1000=35/40=7/8{prima data am amplificat cu 1000, apoi am simplificat pein 25 si apoi prin 5};
7/8=7/8;
6/8=3/4{am simplificat prin 2};
3/4=0,75=6/8;
1,(3)=4/3;
7/8=0,875=7/8;
Acestea sunt perechile de numere egale.
Numerele:-21/24 si -0,75 nu au pereche

Answer 2

numerele egale sunt ingrosate:
3/4
-21/24=-7/8
-0,75=-75/100=-3/4
0,75=3/4
7/8
4/3
0,875=7/8
7/8
6/8=3/4
