Question

Hallar el valor de: “a + b”
a = 8/9
b = 4/6

Answer 1

a + b = 14/9 o 1 con 5/9

_________________________________________________________

a + b → $\frac{8}{9}+\frac{4}{6}$

a + b → $\frac{(8)(6)+(9)(4)}{(9)(6)}$

a + b → $\frac{48 + 36}{54}$

a + b → $\frac{84}{54}$, simplificas sacándole sexta (dividiendo entre 6)

a + b → $\frac{84 : 6}{54: 6}$

a + b → $\frac{14}{9}$  o en numero mixto → $1\frac{5}{9}$
