1] 12/7 = 1 5/7 = 1, 714

2] 3/7 x 100% = (300/7) % = 42,857%

3] 25,175 + 105,50 - 75,60 = 
  25,175
105,50
---------- +
130,675
  75,60
------------ -
  55,075

4] 3/5 x 2 1/4
= 3/5 x 9/4
= 27/20
= 1 7/20

5] 6 : 9/5
= 6 x 5/9
= 30/9
= 3 3/9
= 3 1/3

6] 57/9 = 6 3/9 = 6 1/3

7] 3/5 + 3 1/4 + 2 1/3
= 3 + 2 + (3/5 + 1/4 + 1/3)
= 5 + (36 + 15 + 20)/60
= 5 + 71/60
= 5 + 1 11/60
= 6 11/60
