Question

подскажите как решить уравнение ​

Answer 1

$frac{2}{7} x = 6 frac{2}{7} \ x = frac{6 times 7 + 2}{7} div frac{2}{7} \ x = frac{44}{7} div frac{2}{7} \ x = frac{44}{7} times frac{7}{2} \ x = 22$

проверяем:

$frac{2}{7} times 22 = 6 frac{2}{7} \ frac{44}{7} = frac{6 times 7 + 2}{7} \ frac{44}{7} = frac{44}{7}$
