Question

Помогите пожалуйста
Два примера

Answer 1

1) 5/6 - 2/3 = 5/6 - 4/6 = 1/6

2) 7/8 - 1/2 = 7/8 - 4/8 = 3/8

3) 1/6 * 3/8 = 1/16

4) 1/16 * (-4) = -1/4

ответ: -1/4

===================

1) 3/8 - 1/6 = 9/24 - 4/24 = 5/24

2) 2/9 - 2/5 = 10/45 - 18/45 = -8/45

3) 5/24 * (-8/45) = -1/27

4) -1/27 * 27 = -1

ответ: -1
