44. The fabric shrinks by $\frac{1}{18}$ in length and by $\frac{1}{14}$ in width during washing. What length of fabric should be taken to have $221 \mathrm{~m}^{2}$ after washing, if the width before washing was 875 mm?
44. The width of the material after washing $0.875 \cdot \frac{13}{14}=\frac{7}{8} \cdot \frac{13}{14}=\frac{13}{16}$ (m), length $-221: \frac{13}{16}=272$ (m), which is $\frac{17}{18}$ of the original. Therefore, we need to take $272: \frac{17}{18}=288(\mathrm{M})$.
