Answer 1

Răspuns:

$\frac{1}{3} \div ( \frac{8}{9} - \frac{5}{6} ) = \frac{1}{3} \div ( \frac{32 - 30}{36} ) = \frac{1}{3} \div \frac{2}{36} = \frac{1}{3} \times \frac{36}{2} = \frac{36}{6} = 6$

Sa stii ca acolo cand am scris 32-30 supra 36 am adus la acelasi numitor

Answer 2

Răspuns:

$\frac{1}{3} \times ( \frac{8^{(2} }{9} - \frac{5 {}^{(3} }{6} ) = \frac{1}{3} \times ( \frac{16 - 15}{18} )$

$= > \frac{1}{3} \times \frac{1}{18} = \frac{1 \times 1}{3 \times 18} = \frac{1}{54}$
