\[ \frac{5}{4} + \frac{25}{2} + 4 = \frac{71}{4} = 17.75 \]

The sum can be computed by rewriting each term over a common denominator, where the least common denominator of \(\frac{5}{4}\), \(\frac{25}{2}\), and \(\frac{4}{1}\) is \(4\). \[ \begin{aligned} \frac{5}{4} + \frac{25}{2} + 4 &= \frac{5 \cdot 1}{4 \cdot 1} + \frac{25 \cdot 2}{2 \cdot 2} + \frac{4 \cdot 4}{1 \cdot 4} \\ &= \frac{5 + 50 + 16}{4} \\ &= \frac{71}{4} \end{aligned} \]
