Răspuns

Explicație pas cu pas:

2/5 +1/5 = (2+1) /5 =3/5

1/4 +3/4 = (1+3)/4=4/4

2/11 +4/11 =(2+4)/11=6/11

7/12 + 5/12 = (7+5) /12 =12/12

Answer 2

Salut,


$\frac{2}{5} + \frac{1}{5} = \frac{3}{5}$

$\frac{1}{4} + \frac{3}{4} = \frac{4}{4} = 1$

$\frac{2}{11} + \frac{4}{11} = \frac{6}{11}$

$\frac{7}{12} + \frac{5}{12} = \frac{12}{12} = 1$
