\[ 300 + 70 + 3 + 0.08 + 0.009 = \frac{373089}{1000} = 373.089 \]

The sum can be computed by rewriting each term over a common denominator, where the least common denominator of \(\frac{300}{1}\), \(\frac{70}{1}\), \(\frac{3}{1}\), \(\frac{8}{100}\), and \(\frac{9}{1000}\) is \(1000\). \[ \begin{aligned} 300 + 70 + 3 + 0.08 + 0.009 &= \frac{300 \cdot 1000}{1 \cdot 1000} + \frac{70 \cdot 1000}{1 \cdot 1000} + \frac{3 \cdot 1000}{1 \cdot 1000} + \frac{8 \cdot 10}{100 \cdot 10} + \frac{9 \cdot 1}{1000 \cdot 1} \\ &= \frac{300000 + 70000 + 3000 + 80 + 9}{1000} \\ &= \frac{373089}{1000} \end{aligned} \]
