Răspuns:

$a) \: \frac{2 + 6}{2} = \frac{8}{2} {}^{(2} = 4$

$b) \: \frac{15}{3 + 12} = \frac{15}{15} {}^{(15} = 1$

$c) \: \frac{1 + 2 + 3 + 4}{2 + 4 + 6 + 8} = \frac{10}{20} {}^{(10} = \frac{1}{2}$

$d) \: \frac{1 \times \not2 \times 3 \times\not 4 \times 5}{ \not2 \times \not4 \times 6 \times 8 \times 10} = \frac{\not3 \times \not5}{\not6 \times 8 \times \not10} = \frac{1}{2 \times 8 \times 2} = \frac{1}{32}$

$e) \: \frac{1 \times 2 \times 3 \times 4}{4 \times 8 \times 12 \times 16} = \frac{1}{4 \times 4 \times 4 \times 4} = \frac{1}{4 {}^{4} }$

$f) \: \frac{20 + 10 + 50}{150} = \frac{80}{150} {}^{(10} = \frac{8}{15}$
