Solution

$⇒$Here, we have to determine the length of the skirt, if the hem is let down$⇒$On converting the given mixed fractions into an improper fraction we obtain:$\therefore$ Length of the skirt $=35\frac{7}{8}=\frac{8×35+7}{8}=\frac{287}{8}\mathrm{cm}$ Dimension of hem = $=3\frac{1}{8}=\frac{8×3+1}{8}=\frac{25}{8}\mathrm{cm}$$\therefore$Length of skirt, if the hem is let down $=\frac{287}{8}+\frac{25}{8}$ $=\frac{312}{8}\mathrm{cm}$ $=39\mathrm{cm}$Therefore, The length of the skirt, if the hem is let down is equal to $39\mathrm{cm}$
