Răspuns:
a) 28; b) 6
Explicație pas cu pas:
a)
[tex]33a = 21b \iff 11a = 7b \iff \frac{a}{b} = \frac{7}{11} \\ \frac{a}{b} = \frac{n}{44} \iff \frac{7}{11} = \frac{n}{44} \\ n = \frac{7 \cdot 44}{11} \implies \bf n = 28[/tex]
b)
[tex]55a = 5b \iff 11a = b \iff \frac{a}{b} = \frac{1}{11} \\ \frac{a}{b} = \frac{n}{66} \iff \frac{1}{11} = \frac{n}{66} \\ n = \frac{66}{11} \implies \bf n = 6[/tex]
