Explanation:

Step1: Convert mixed - numbers to improper fractions

$10\frac{9}{10}=\frac{10\times10 + 9}{10}=\frac{109}{10}$ and $9\frac{3}{10}=\frac{9\times10+3}{10}=\frac{93}{10}$

Step2: Add the two fractions

$\frac{109}{10}+\frac{93}{10}=\frac{109 + 93}{10}=\frac{202}{10}$

Step3: Simplify the fraction

$\frac{202}{10}=\frac{101}{5}=20\frac{1}{5}$

Answer:

$20\frac{1}{5}$
