A scale of the Eiffel Tower represents it as being 3 centimeters tall when in reality it is 15 meters tall. What scale is the drawing using? \(1 \, centimeter \, = \, 5 \, meters\)

\(1 \, centimeter \, = \, 5 \, meters\)

\(1 \, centimeter \, = \, 7 \, meters\)

\(1 \, centimeter \, = \, 4 \, meters\)

\(1 \, centimeter \, = \, 5 \, meters\)

\(1 \, centimeter \, = \, 3 \, meters\)

Ashley's dad has a to-scale model of a space rocket. The rocket is 2 inches tall. Her dad tells her that the real rocket was 8 yards tall. What scale does the model use? \(1 \, inch \, = \, 4 \, yards\)

\(1 \, inch \, = \, 4 \, yards\)

\(1 \, inch \, = \, 7 \, yards\)

\(1 \, inch \, = \, 3 \, yards\)

\(1 \, inch \, = \, 1 \, yard\)

\(1 \, inch \, = \, 4 \, yards\)
