Answer 1

8 5/6 + 5 3/8=8 40/48 + 5 18/48=13 58/48=14 10/58
7 2/3 - 4 2/5=7 10/15 - 4 6/15=3 4/15
1 2/7 X 41/12=9/7 X 41/12=108/84 X 287/84=30996/84= po skroceniu 369
4 8/15 : 3 2/5=68/15 : 17/5=68/15 X 5/17=340/75=po skroceniu 4 40/75

Answer 2

8 5/6 + 5 3/8 = 53/6 + 43/8 = 424/48 + 258/48 = 682/48 = 14 i 10/48 = 14 i 5/24
7 2/3 - 4 2/5 = 23/3 - 22/5 = 115/15 - 66/15 = 49/15 = 3 i 4/15
1 2/7 X 41/12 = 9/7 * 41/12 = 123/28 = 4 i 11/28
4 8/15 : 3 2/5 = 68/15 : 17/5 = 68/15 * 5/17 = 68/51 = 1 i 17/51
