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

Answer 1

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
