\[ 28.56 + 7.8 + 9.67 + 46 = \frac{9203}{100} = 92.03 \]

The sum can be computed by rewriting each term over a common denominator, where the least common denominator of \(\frac{28}{1}\), \(\frac{56}{100}\), \(\frac{7}{1}\), \(\frac{8}{10}\), \(\frac{9}{1}\), \(\frac{67}{100}\), and \(\frac{46}{1}\) is \(100\). \[ \begin{aligned} 28.56 + 7.8 + 9.67 + 46 &= \frac{28 \cdot 100}{1 \cdot 100} + \frac{56 \cdot 1}{100 \cdot 1} + \frac{7 \cdot 100}{1 \cdot 100} + \frac{8 \cdot 10}{10 \cdot 10} + \frac{9 \cdot 100}{1 \cdot 100} + \frac{67 \cdot 1}{100 \cdot 1} + \frac{46 \cdot 100}{1 \cdot 100} \\ &= \frac{2800 + 56 + 700 + 80 + 900 + 67 + 4600}{100} \\ &= \frac{9203}{100} \end{aligned} \]
