Question

punctele d),f) si h) va rog mult

Answer 1

d) c.m.m.m.c. (5, 10, 15) = 30

$\displaystyle =\frac{^{6)} 2}{5} -\frac{^{2)}4}{15} -\frac{^{3)}3}{10} =\frac{12-8-9}{30} =-\frac{5^{(5} }{30} =-\frac{1}{6}$

e) c.m.m.m.c. (18, 2, 9) = 18

$\displaystyle =\frac{ 5}{18} -\frac{^{9)}3}{2} -\frac{^{2)}13}{9} =\frac{5-27-26}{18} =-\frac{48^{(2} }{18} =-\frac{24}{9}$

f) c.m.m.m.c. (4, 5, 2) = 20

$\displaystyle =\frac{^{5)}5}{4} -\frac{^{4)}4}{5} +\frac{^{10)}1}{2} =\frac{25-16+10}{20} =\frac{19}{20}$
