Explanation:

Step1: Find common denominator

The denominators are 5 and 10; the least common denominator is 10. Convert $\frac{1}{5}$ to tenths:
$\frac{1}{5} = \frac{1\times2}{5\times2} = \frac{2}{10}$

Step2: Add the two fractions

Add the fraction for January and February:
$\frac{2}{10} + \frac{7}{10} = \frac{2+7}{10} = \frac{9}{10}$

Answer:

$\frac{9}{10}$ of her quarterly sales goal
