Answer 1

1) 25\28 - 5\14 = 25\28 - 10\28 = 15\28 
2) 5\7 - 1\4 = 20\28 - 7\28 = 13\28 
3) 15\28 - 13\28 - 1\28 = 1\28
ОТВЕТ: 1\28

Answer 2

To simplify the expression, we can first find a common denominator for all the fractions involved:

25/28 - 5/14 = (252)/(282) - (54)/(144) = 50/56 - 20/56 = 30/56 = 15/28

5/7 - 1/4 = (54)/(74) - (17)/(47) = 20/28 - 7/28 = 13/28

Putting it all together:

(15/28) - (13/28) - (1/28) = 14/28 - 1/28 = 13/28

Therefore, the value of the expression is 13/28.
