1 7/8 + 3 3/6 = 1 14/16 + 3 9/16 = 5 7/16
2 6/7 - 1 3/4 + 1/4 = 2 24/28 - 1 21/28 + 7/28 = 1 10/28 = 1 5/14
1 8/12 + 4/1 * 6/9 = 1 8/12 + 2 6/9 = 1 2/3 + 2 2/3 = 3 4/3 = 4 1/3
1 7/10 * 4/34 = 17/10 * 4/34 = 1/5 * 1/1 = 1/5
(2 3/7 + 1 4/6) - (5 6/10 - 4 3/5) =
= 2 3/7 + 1 4/6 - 5 6/10 + 4 3/5 =
= 2 3/7 + 1 2/3 - 5 3/5 + 4 3/5 =
= 2 9/21 + 1 14/21 - 1 = 2 23/21 = 3 2/21
mam nadzieje, ze pomoglam
