Question

Arătați că 2/5 x (2/3 + 1) - (2 - 4/3) = 0

Answer 1

Explicație pas cu pas:

$\frac{2}{5} \times ( \frac{2}{3} + 1) - (2 - \frac{4}{3} ) = 0 \\ \frac{2}{5} \times ( \frac{2}{3} + \frac{3}{3} ) - ( \frac{6}{3} - \frac{4}{3} ) = 0 \\ \frac{2}{5} \times \frac{5}{3} - \frac{2}{3} = 0 \\ \frac{2}{3} - \frac{2}{3} = 0$
