Mackenzie needs to determine whether the rectangles are proportional. Which process could she use? Check all that apply. A pre-image rectangle has a length of 4 and width of 3. An image rectangle has a length of 2 and width of 1.5.
She could compare the ratios of the sides of the pre-image to the corresponding sides of the image in the proportion StartFraction 3 Over 1.5 EndFraction = StartFraction 4 Over 2 EndFraction.
She could verify that adding the same number to each side in the pre-image does not result in the corresponding side length of the image.
She could verify that multiplying each side in the pre-image by One-half results in the length of the corresponding side in the image.
She could verify that subtracting the same number to each side in the pre-image does not result in the corresponding side length of the image.
She could just notice that all the sides in the pre-image are whole numbers so all the sides in the image should be whole numbers.
