\[ 67 + 3.751 = \frac{70751}{1000} = 70.751 \]

The sum can be computed by rewriting each term over a common denominator, where the least common denominator of \(\frac{67}{1}\), \(\frac{3}{1}\), and \(\frac{751}{1000}\) is \(1000\). \[ \begin{aligned} 67 + 3.751 &= \frac{67 \cdot 1000}{1 \cdot 1000} + \frac{3 \cdot 1000}{1 \cdot 1000} + \frac{751 \cdot 1}{1000 \cdot 1} \\ &= \frac{67000 + 3000 + 751}{1000} \\ &= \frac{70751}{1000} \end{aligned} \]
