Explicație pas cu pas:
e)
cmmmc(5,7) = 5 · 7 = 35
[tex]\frac{11}{5} +\frac{3}{7} =\frac{11*7+3*5}{35} =\frac{92}{35} [/tex]
f)
cmmmc(11,19) = 11 · 19 = 209
[tex]\frac{1}{11} +\frac{5}{19} =\frac{1*19+5*11}{209} =\frac{74}{209} [/tex]
g)
cmmmc(5,23) = 5 · 23 = 115
[tex]\frac{3}{5} +\frac{1}{23} =\frac{3*23+1*5}{209} =\frac{74}{115} [/tex]
