a)
x = 9/12 - 11/43
x = 3/4 - 11/43
x = 129/172 - 44/172
x = 85/172
----------------
б)
y = 21/34 - 16/51
y = 63/102 - 32/102
y= 31/102
-------------------
в)
a = 21/78 - 4/39
a = 21/78 - 8/78
a = 13/78
a = 1/6
-------------
г)
x = 45/62 - 36/155
x = 225/310 - 72/310
x = 153/310
-----------------
д)
y = 173/178 - 77/89
y = 173/178 - 154/178
y = 19/178

----------------------
е)
a = 19/21 - 14/210
a = 190/210 - 14/210
a = 176/210
a= 88/105
