Question

Calculați a 5/6 din 300 b 2/3 din 600 c 4/7 din 1400​

Answer 1

Răspuns:

$\frac{5}{6} \times 300 = \frac{5}{6} \times \frac{300}{1} = \frac{1500}{6} = 250$

$\frac{2}{3} \times 600 = \frac{2}{3} \times \frac{600}{1} = \frac{1200}{3} = 400$

$\frac{4}{7} \times 1400 = \frac{4}{7} \times \frac{1400}{1} = \frac{5600}{7} = 800$
