Answer 1

Răspuns:

$a) \: \frac{1}{2} : \frac{3}{ 2} = \frac{1}{ \not2} \cdot \frac{ \not2}{3} = \frac{1}{3}$

$\frac{1}{3} : \frac{4}{3} = \frac{1}{ \not3} \cdot \frac{ \not3}{4} = \frac{1}{4}$

$\frac{1}{4} : \frac{5}{4} = \frac{1}{ \not4} \cdot \frac{ \not4}{5} = \frac{1}{5}$

$\frac{1}{5} : \frac{6}{5} = \frac{1}{ \not5} \cdot \frac{ \not5}{6} = \frac{1}{6}$

$b) \: \frac{125}{34} : \frac{50}{51} = \frac{ \not125}{ \not34} \cdot \frac{ \not51}{ \not50} = \frac{5}{2} \cdot \frac{3}{2} = \frac{15}{4}$

$\frac{15}{4} : ( \frac{3}{2} ) ^{2} = \frac{15}{4} : \frac{9}{4} = \frac{ \not15}{ \not4} \cdot \frac{ \not4}{ \not9} = 5 \cdot \frac{1}{3} = \frac{5}{3}$

$\frac{ {}^{5)} 5}{3} + \frac{ {}^{3)} 2}{5} = \frac{25 + 6}{15} = \frac{31}{15}$

$\frac{31}{15} : \frac{14}{10} = \frac{31}{15} \cdot \frac{10 {}^{(2} }{14} = \frac{31}{ \not15} \cdot \frac{ \not5}{7} = \frac{31}{3} \cdot \frac{1}{7} = \frac{31}{21}$
