Answer 1

Răspuns:

Explicație pas cu pas:

e)

cmmmc(5,7) = 5 · 7 = 35

$\frac{11}{5} +\frac{3}{7} =\frac{11*7+3*5}{35} =\frac{92}{35}$

f)

cmmmc(11,19) = 11 · 19 = 209

$\frac{1}{11} +\frac{5}{19} =\frac{1*19+5*11}{209} =\frac{74}{209}$

g)

cmmmc(5,23) = 5 · 23 = 115

$\frac{3}{5} +\frac{1}{23} =\frac{3*23+1*5}{209} =\frac{74}{115}$
