Question

Решить уравнение:
12,5 х - 12 1/3 х = 133 3/4

Answer 1

Ответ:

$12 \frac{1}{2} x - 12 \frac{1}{3} x = 133 \frac{3}{4} \\ 12 \frac{3}{6} - 12 \frac{2}{6} = \frac{1}{6} \\ \frac{1}{6} x = 133 \frac{3}{4} \\ x = 133 \frac{3}{4} \div \frac{1}{6} \\ x = \frac{535}{4} \times 6 \\ x = \frac{1605}{2} \\ x = 802.5$
