7/8 - 2/3. 3/4 - 4/7. 9/16 - 11/24. 11/12 - 11/18. Помогите

Answer 1

7/8 - 2/3 = 21 - 16/24 = 5/24
3/4 - 4/7 = 21 - 16/28 = 5/28
9/16 - 11/24 = 27 - 22/48 = 5/48
11/12 - 11/18 = 33 - 22/36 = 11/36

Answer 2

7|8 - 2|3=21|24 - 16|24=5|24

3|4 - 4|7=21|28 - 12|28=9|28

9|16 - 11|24=216|384 - 176|384=40|384

11|12 - 11|18 =198|216 - 132|216=66|216
