Question

Efectueaza adunarile urmatoare : 1/4+2/4 , 1/6+5/6 , 3/4+2/4 , 4/8+3/8

Answer 1

1/4 + 2/4 = 3/4
1/6 + 5/6 = 6/6 = 1
3/4 + 2/4 = 5/4
4/8 + 3/8 = 7/8
Daca fractiile au acelasi numitor, se aduna numaratorii iar numitorul ramane acelasi.

Answer 2

$\frac{1}{4} + \frac{2}{4} = \frac{3}{4} \\ \\ \frac{1}{6} + \frac{5}{6} = \frac{6}{6} =1 \\ \\ \frac{3}{4} + \frac{2}{4} = \frac{5}{4} \\ \\ \frac{4}{8} + \frac{3}{8} = \frac{7}{8}$
