Respuesta:

Explicación paso a paso:

a. r + 1/3 = 8/3

r = 8/3 - 1/3

r = 7/3

b. x + 2/3 = 6/6

x = 6/6 - 2/3

x = [ (6 x 3) - (6 x 2) ]/ (6 x 3)

x = [18 - 12] / 18

x = 6/18

x = 1/3

c. x - 3/8 = 1/4

x = 1/4 + 3/8

x = [ (1 x 8) + (4 x 3) ]/ (4 x 8)

x = [8 + 12] / 32

x = 20/32

x= 5/8

d. x - 5/6 = 7/8

x = 7/8 + 5/6

x = [ (7 x 6) + (8 x 5) ]/ (8 x 6)

x = [42 + 40] / 48

x = 82/48

x = 41/24

e. a + 4/5 = 13/10

a = 13/10- 4/5

a = [ (13 x 5) - (10 x 4) ]/ (10 x 5)

a = [65 - 40] / 50

a = 25/50

a = 1/2

f. y - 3/4 = 5/6

y = 5/6 + 3/4

y = [ (5 x 4) + (6 x 3) ]/ (6 x 4)

y = [20 + 18 / 24

y = 38/24

y = 19/12
