Question

Вопрос:

3) 1 1/22 * 3 2/3 - (2 5/6 + 3 5/6 * 7/23) : 3/5;

Accepted Answer

3) 1 1/22 * 3 2/3 - (2 5/6 + 3 5/6 * 7/23) : 3/5 = 23/22 * 11/3 - (17/6 + 23/6 * 7/23) : 3/5 = (23 * 11)/(22 * 3) - (17/6 + (23 * 7)/(6 * 23)) : 3/5 = (23 * 11)/(11 * 2 * 3) - (17/6 + 7/6) : 3/5 = 23/6 - (17 + 7)/6 : 3/5 = 23/6 - 24/6 : 3/5 = 23/6 - 4 * 5/3 = 23/6 - 20/3 = 23/6 - (20 * 2)/(3 * 2) = 23/6 - 40/6 = (23 - 40)/6 = -17/6 = -2 5/6

Ответ: -2 5/6
