Відповідь:

Покрокове пояснення:

Спочатку згрупуємо подібні доданки, тобто об'єднаємо всі доданки, що містять змінну a, та всі доданки, що містять змінну b:

(-5/6a + 7/12a) + (7/8b - 5/12b)

Тепер можна скористатися правилом додавання дробів з різними знаменниками та спростити дроби до спільного знаменника:

(-10/12a + 7/12a) + (21/24b - 10/24b)

Після спрощення доданків залишається:

(-1/6)*a + (11/24)*b
