Answer 1

Răspuns:

se aduna numaratorii apoi se imparte la numarator

a)  $\frac{4+11}{15}$ +$\frac{9+41}{10}$= $\frac{15}{15}$ + $\frac{50}{10}$= 1+ 5= 6

b) $\frac{17+15}{16}$ + $\frac{12+14}{13}$= $\frac{32}{16}$ + $\frac{26}{13}$= 2 + 2= 4

c) $\frac{5+3+1}{8}$ + $\frac{7+11}{18}$= $\frac{9}{8}$ + $\frac{18}{18}$=  $\frac{9}{8} + 1$= $\frac{9+8}{8}$= $\frac{17}{8}$

d) $\frac{8+5+1}{14}$ + $\frac{3}{3}$= $\frac{14}{14}$ + 1= 1+1 = 2
