The denominators are 9 and 5. The least common denominator is $9\times5 = 45$.
Rewrite the fractions: $\frac{7}{9}=\frac{7\times5}{9\times5}=\frac{35}{45}$, $\frac{4}{5}=\frac{4\times9}{5\times9}=\frac{36}{45}$

Step2: Add the fractions

Add the numerators: $\frac{35}{45}+\frac{36}{45}=\frac{35 + 36}{45}=\frac{71}{45}$

Answer:

$\frac{71}{45}$
