Răspuns:

$a) \: \frac{7}{5} + \frac{9}{15} = \frac{21}{15} + \frac{9}{15} = \frac{30}{15} = 2$

$b) \: \frac{307}{17} - \frac{290}{17} = \frac{17}{17} = 1$

$c) \: \frac{95}{81} \times \frac{27}{49} = \frac{95}{3} \times \frac{1}{49} = \frac{95}{147}$

$d) \: \frac{102}{47} \div \frac{61}{47} = \frac{102}{47} \times \frac{47}{61} = \frac{102}{1} \times \frac{1}{61} \\ = \frac{102}{61}$

$e) \: ( \frac{14}{15} )^{2} = \frac{ {14}^{2} }{{15}^{2} } = \frac{196}{225}$

$f) \: ( \frac{2001}{3002} ) ^{0} = 1$
