3) Propias son : 4/5 ; 3/8 ; 2/11 ; 1/10
4) a + b + c =20
5)
a) 4/10 = 8/20
b) 6/7 < 3/2
c) 5/9 < 4/7
d) 8/5 > 4/7
e) 8/9 < 6/5
Explicación paso a paso:
6 / a - 2 = 10/9 = 17 / b + 3 = 1/ 3c
54 = 10a - 20
10a = 74
a = 7,4
---------
10b + 30 = 153
10b = 123
b = 12,3
-------
30c = 9
c = 0,3
----
a + b + c = 7,4 + 12,3 + 0,3 = 20
