Question

Найдите неизвестное.

x + 5 целых 1/6 = 7
9 целых 2/3 - x = 5
x - 1/3 = 2 целых 1/6

Answer 1

Ответ:

$x + 5 \frac{1}{6} = 7 \\ x = 7 - 5 \frac{1}{6} \\ x = 2 \frac{1}{6} \\ \\ 9 \frac{2}{3} - x = 5 \\ x = 9 \frac{2}{3} - 5 \\ x = 4 \frac{2}{3} \\ \\ x - \frac{1}{3} = 2 \frac{1}{6} \\ x = 2 \frac{1}{6} - \frac{1}{3} \\ x = 1 \frac{5}{6}$
