Ответ:

$\frac{17.9}{1 \frac{1}{4} } = \frac{u}{0.25} \\ \frac{ \frac{179}{10} }{ \frac{5}{4} } = \frac{u}{ \frac{1}{4} } \\ \frac{179 \times 4}{10 \times 5} = 4u \\ \frac{358}{25} = 4u \\ u = \frac{358}{25} \times \frac{1}{4} = \frac{179}{25} \times \frac{1}{2} = \frac{179}{50} \\ u = \frac{179}{50} = 3 \frac{29}{50}$
