Answer 1

5,68 - 1 3/14 + 2,12 - 5 9/14  =
= 5 68/100 - 1 3/14 + 2 12/100 - 5 9/14 =
= 5 952/1400 - 1 300/1400 + 2 168/1400 - 5 900/1400 =
= 4 652/1400 + 2 168/1400 - 5 900/1400 =
= 6 820/1400 - 5 900/1400 =
= 1320/1400 =
= 132/140 =
= 33/35


5,8 - 5 8/9 + 3,4 - 3 3/27 =
= 5 8/10 - 5 8/9 + 3 4/10 - 3 3/27 =
= 5 72/90 - (5 80/90 + 3 36/90) - 3 3/27 =
=  5 72/90 - 8 116/90 - 3 3/27 =
= 5 72/90 - 9 26/90 - 3 3/27 =
= - 4 46/90 - 3 3/27 =
= - 4 1242/2430 - 3 270/2430 =
= - 7 1512/2430 =
= - 7 756/1215 =
= - 7 252/405
