Помогите решить уравнение n-10 7/12=3 1/6

n - 10 7/12 = 3 1/6 n - 127/12 = 19/6 n = 19/6 + 127/12 n = 19*2/6*2 + 127/12 n = 38/12 + 127/12 n = 165/12 n = 13 9/12 n = 13 3/4 проверка: 13 3/4 - 10 7/12 = 3 1/6 55/4 - 127/12 = 19/6 55*3/4*3 - 127/12 = 19*2/6*2 165/12 - 127/12 = 38/12 38/12 = 38/12 3 2/12 = 3 2/12 3 1/6 = 3 1/6
