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

n - 10 7/12 = 3 1/6n - 127/12 = 19/6n = 19/6 + 127/12n = 19*2/6*2 + 127/12n = 38/12 + 127/12n = 165/12n = 13 9/12n = 13 3/4проверка:13 3/4 - 10 7/12 = 3 1/655/4 - 127/12 = 19/655*3/4*3 - 127/12 = 19*2/6*2165/12 - 127/12 = 38/1238/12 = 38/123 2/12 = 3 2/123 1/6 = 3 1/6
