El número decimal 1,3 lo expresamos en fracción como 13/10

El inverso de esa fracción es otra fracción pero los números de arriba y abajo se intercambian

→ El inverso de 13/10 es 10/13

Ahora hacemos la suma

[tex] \frac{13}{10} + \frac{10}{13} [/tex]

[tex] \frac{13\cdot 13+ 10 \cdot 10}{10\cdot 13}[/tex]

[tex] \frac{169+ 100}{130}[/tex]

[tex] \boxed{\frac{269}{130}}[/tex]

El valor decimal

[tex] \boxed{2,0\overline{692307}} [/tex]
