1 și 3 repede! Va rog! ​

Answer 1

Răspuns:

1.

$\frac{4(2}{2} =\frac{6(3}{3}$ ⇒ 2=2  Adevarat

$\frac{3)5}{7} =\frac{15}{21}  ⇒ \frac{15}{21}=\frac{15}{21}  Adevarat$

$\frac{5)1}{12} =\frac{2)5}{30}  ⇒ \frac{5}{60}=\frac{10}{30}  Fals$

$\frac{2)3}{17} =\frac{6}{34}  ⇒ \frac{6}{34}=\frac{6}{34}  Adevarat$

$\frac{11)11}{4} =\frac{2)33}{22}  ⇒ \frac{121}{44}=\frac{66}{44}  Fals$

3.a) $\frac{3)3}{7} =\frac{9}{21}$

b)$\frac{4)5}{4} =\frac{20}{16}$

c)$\frac{1}{9} =\frac{3(3}{27}$

d)$\frac{4}{4} =\frac{7}{7} =1$
