\[\boxed{\mathbf{117}.}\]
\[Пусть\ x - одно\ число;\ \]
\[(x + 5) - второе\ число.\]
\[Составим\ уравнение:\]
\[2x(x + 5) = 5,5\]
\[2x^{2} + 10x - 5,5 = 0\ \ \ | \cdot 2\]
\[4x^{2} + 20x - 11 = 0\]
\[D_{1} = 100 + 44 = 144\]
\[x_{1} = \frac{- 10 + 12}{4} = \frac{2}{1} + 4 = 0,5;\ \ \]
\[x_{2} = \frac{- 10 - 12}{4} = - \frac{22}{4} = - 5,5.\]
\[x + 5 = 0,5 + 5 = 5,5;\]
\[x + 5 = - 5,5 + 5 = - 0,5.\]
\[Ответ:0,5\ и\ 5,5;\ - 5,5\ и\ ( - 0,5).\]
