1)
(18,14-20,49)-(-3,35) = 3
2/7+(-5 2/3) +5 5/7
= (-2, 35)+(3, 35) =3
2/7+(-5 2/3) +5 5/7
= (-2, 35) +3, 35 = 3
2/7-(5 2/3)+5 5/7
= (-2, 35)+3, 35 = 3
2/7-5 2/3+5 5/7
= (-2, 35)+3, 35 = 3
2/7-5 2/3+40/7
= -2, 35+3, 35 = 3
2/7- 5 2/3+40/7
= -2, 35+3, 35 = 3
2/7-17/3+40/7
= 1 = 3
2/2-17/3+40/7
= 1
1 = 3

3=3

61/11-5,5+3 1/22 = 1,5
(22,19-40,2)-(-20,19)
= 61/11-11/2+3 1/22
(22,19-40,2)-(-20,19) =1,5
= 61/11-11/2+67/22
(22, 1) -40, 2) -(-20, 19) = 1,5
= 61/11-11/2+67/22
(-18, 01) -(-20, 19) = 1,5
= 61/11-11/2+67/22
(-18, 01) +20, 19 = 1,5
= 61/11-11/2+67/22
(-18, 01) +20, 19 = 3/2
= 34

-18, 01+20, 19 = 3/2
