Решите примеры: б) 2-(13/33-5/22) е)(63 2/3 + 3 1/8)- (13-10 5/9)

2- (13/33-5/22)=
1) 13/33 - 5/22 = 26/66 - 15/66= 11/66 = 1/6
2) 2 - 1/6 = 2/1 - 1/6 = 12/6 - 1/6 = 11/6= 1 5/6

(63 2/3 + 3 1/8) - (13 - 10 5/9)=
1) 63 2/3 + 3 1/8 = 191/3 + 25/8 = 1528/24 + 75/24 = 1603/24 = 66 19/24
2) 13-10 5/9 = 13/1 - 95/9 = 117/9 - 95/9=22/9 = 2 4/9
3) 66 19/24 - 2 4/9 = 1603/24 - 22/9=4809/72 - 176/72=4633/72 = 64 25/72
