Explanation:

Step1: Find common denominator

The common denominator of 5 and 9 is 45. So $\frac{3}{5}+\frac{5}{9}=\frac{3\times9}{5\times9}+\frac{5\times5}{9\times5}=\frac{27}{45}+\frac{25}{45}$.

Step2: Add numerators

$\frac{27}{45}+\frac{25}{45}=\frac{27 + 25}{45}=\frac{52}{45}$.

Step3: Convert to mixed - number

$52\div45 = 1$ with a remainder of 7. So $\frac{52}{45}=1\frac{7}{45}$.

Answer:

$1\frac{7}{45}$
