Reminder Round all answers to two decimal places unless otherwise indicated.

Skirt Length One author's analyzed skirt lengths in the United Kingdom (UK) and Germany. To get a standardized measure of skirt length, she calculated the ratio.

$\frac{\text{Length}\text{from}\text{shoulder}\text{to}\text{skirt}\text{hem}}{\text{Length}\text{from}\text{shoulder}\text{to}\text{ankle}}$

The article includes the following graph of the ratio for skirt length in terms of the year. In the graph, the solid line is the ratio in the UK, and the dashed line is the ratio in Germany.

FIGURE $1.32$ Ratio for skirt length

a. Does a larger ratio indicate a longer or a shorter skirt?

b. When were skirt lengths shortest in the UK?

c. In this period, did skirt lengths in either Germany or the UK ever reach to the ankle?
