The ratio of the width to the length of the swimming pool with a width of 5.5 yards and a length of 7.5 yards is 11/15 yards, which corresponds to answer D) 11/15 yards.
The student has asked to find the ratio of the width to the length of a rectangular swimming pool where the width is 5.5 yards and the length is 7.5 yards. To find this ratio, we divide the width by the length:
Ratio = Width / Length = 5.5 yards / 7.5 yards. Simplifying this we get:
Ratio = 11/15 yards.
Therefore, the correct answer is D) 11/15 yards.
