Answer:

55/9

Step-by-step explanation:

[tex]5+\dfrac79+\dfrac{4}{12}=\dfrac51+\dfrac79+\dfrac{4}{12}[/tex]

We need to make the denominators the same:

[tex]\implies\dfrac{5\times 36}{1\times 36}+\dfrac{7\times 4}{9\times 4}+\dfrac{4\times 3}{12\times 3}=\dfrac{180}{36}+\dfrac{28}{36}+\dfrac{12}{36}[/tex]

Now simply add the numerators:

[tex]\implies \dfrac{180}{36}+\dfrac{28}{36}+\dfrac{12}{36}=\dfrac{220}{36}[/tex]

Simplify by reducing:

[tex]\implies \dfrac{220}{36}=\dfrac{55}{9}[/tex]

Solution as a mixed number:  [tex]6\frac19[/tex]
