Answer:

C. $1\frac{2}{10}$

Step-by-step explanation:

$\frac{30}{100}+\frac{9}{10}=\frac{30}{100}+\frac{90}{100}$

$\frac{30}{100}+\frac{90}{100}=\frac{120}{100}$

$\frac{120}{100}=1\frac{20}{100}$

$1\frac{20}{100}=1\frac{2}{10}$

Explanation:

$\frac{300}{100} + \frac{9}{10}$

$\frac{30}{10} + \frac{9}{10}$

$\frac{3 + 9}{10}$

$\frac{3 + 9}{10} = \frac{12}{10}$
