ayudaa!! si puede ser con cuenta mejor
Respuestas a la pregunta
1.
a + b
2/3 + 3/4 = a + b
17/12 = a + b
b + c
3/4 + 5/6 = b + c
19/12 = b + c
a + c
2/3 + 5/6 = a + c
3/2 = a + c
a + b + c
2/3 + 3/4 + 5/6 = a + b + c
9/4 = a + b + c
2.
a = 3/5
a + b = 7/10
3/5 + b = 7/10
b = 7/10 - 3/5
b = 1/10
a + c = 1 1/10
3/5 + c = 1 1/10
c = 1 1/10 - 3/5
c = -1/2
b + c
1/10 + -1/2 = b + c
-2/5 = b + c
a + b + c
3/5 + 1/10 + -1/2 = a + b + c
1/5 = a + b + c
3.
b + c = 2 3/4
5/2 + c = 2 3/4
c = 2 3/4 - 5/2
c = -1
a + c = 5/8
a - 1 = 5/8
a = 5/8 + 1
a = 13/8
a + b
13/8 + 5/2 = a + b
33/8 = a + b
a + b + c
13/8 + 5/2 + -1 = a + b + c
25/8 = a + b + c
4.
b + c = 1 13/20
b + 5/4 = 1 13/20
b = 1 13/20 - 5/4
b = -3/5
a + b + c = 1 49/60
a - 3/5 + 5/4 = 1 49/60
a = 1 49/60 + 3/5 - 5/4
a = 1/6
a + b
1/6 - 3/5 = a + b
-13/30 = a + b
a + c
1/6 + 5/4 = a + c
17/12 = a + c
5.
b + c = 1
b = 1 - c
a + c = 7/9
a = 7/9 - c
a + b + c = 4/3
7/9 - c + 1 - c - c = 4/3
16/9 - 3c = 4/3
-3c = 4/3 - 16/9
-3c = -4/9
c = -4/9 / -3
c = 4/27
b + c = 1
b + 4/27 = 1
b = 1 - 4/27
b = 23/27
a + c = 7/9
a + 4/27 = 7/9
a = 7/9 - 4/27
a = 17/27
a + b
17/27 + 13/27 = a + b
10/9 = a + b
