Question

Si R = 2 + 1/2 y S = 3 + 5/9
calcula: R+S.
a) 91/18
c) 37/65
b) 17/15
d) 15/13
e) 109/18​

Answer 1

Respuesta:

e) 109/18

Explicación paso a paso:

R = 2 + 1/2 = (2 . 2 + 1) / 2 = (4 + 1) / 2 = 5/2

S = 3 + 5/9 = (3 . 9 + 5) / 9 = (27 + 5) / 9 = 32/9

R + S = 5/2 + 32/9 = (5 . 9 + 32 . 2) / (2 . 9) = (45 + 64) / 18 = 109/18

Rpta.: e) 109/18
