Question

Какая из данных разностей наименьшая 11/12-3/4, 3/4-5/12, 11/12-4/5, 4/5-5/12

Answer 1

11/12 - 3/4 = 11/12 - 9/12 = 2/12 = 1/6 
3/4 - 5/12 = 9/12 - 5/12 = 4/12 = 1/3 
11/12 - 4/5 = 55/60 - 48/60 = 7/60 
4/5 - 5/12 = 48/60 - 25/60 = 23/60 
----------------------------------------------------
1/6 = 10/60 
1/3 = 20/60 
7/60 
23/60 
7 < 10 < 20 < 23 
Ответ ( 11/12 ) - 4/5
