Numerele naturale ≤ 10 sunt: 1, 2, 3, 4, 5, 6, 7, 8, 9, 10.

Observatie: Nu folosesc numarul 0,

Numitorul unei fractii nu poate fi 0. Daca numitorul unei fractii este 0, fractia nu este definita.

1  → numarator
---- → linie de fractie
4  → numitor

a) 1/4; 2/8  → 4 = 4 x 1; 8 = 4 x 2

b) 2/1; 4/2; 6/3; 8/4; 10/5 → numaratoru = dublul numitorului

c) 1/3; 3/5; 5/7; 7/9 → numaratorul, respectiv numitorul sunt numere consecutive impare

d) 1/1; 2/2; 3/3; 4/4; 5/5; 6/6; 7/7; 8/8; 9/9; 10/10 → fractii echiunitare, numaratorul egal cu numitorul

e) 2/3; 4/5; 6/7; 8/9 → numaratorul numar par mai mic decat numitorul
