Explicație pas cu pas:
a)
cmmmc [2; 15] = 2 × 3 × 5 = 30
[tex]\bf \dfrac{^{15)}1~}{2} ~~si ~~\dfrac{^{2)}7}{15} \implies \dfrac{15}{30} ~~si ~~\dfrac{14}{30}[/tex]
b)
cmmmc [4; 25] = 2² × 5² = 100
[tex]\bf \dfrac{^{25)}3~~}{4} ~~si ~~\dfrac{^{4)}16}{25} \implies \dfrac{75}{100} ~~si ~~\dfrac{64}{100}[/tex]
c)
cmmmc [14; 9] = 2 × 3² × 7 = 126
[tex]\bf \dfrac{^{9)}3~~}{14} ~~si ~~\dfrac{^{14)}2~}{9} \implies \dfrac{27}{126} ~~si ~~\dfrac{28}{126}[/tex]
d)
cmmmc [12; 5] = 3 × 2² × 5 = 60
[tex]\bf \dfrac{^{5)}7~~}{12} ~~si ~~\dfrac{^{12)}8~}{5} \implies \dfrac{35}{60} ~~si ~~\dfrac{96}{60}[/tex]
