\[ 2.0156 + 15.999 = \frac{90073}{5000} = 18.0146 \]

The sum can be computed by rewriting each term over a common denominator, where the least common denominator of \(\frac{2}{1}\), \(\frac{156}{10000}\), \(\frac{15}{1}\), and \(\frac{999}{1000}\) is \(10000\). \[ \begin{aligned} 2.0156 + 15.999 &= \frac{2 \cdot 10000}{1 \cdot 10000} + \frac{156 \cdot 1}{10000 \cdot 1} + \frac{15 \cdot 10000}{1 \cdot 10000} + \frac{999 \cdot 10}{1000 \cdot 10} \\ &= \frac{20000 + 156 + 150000 + 9990}{10000} \\ &= \frac{180146}{10000} \\&= \frac{90073}{5000} \end{aligned} \]
