Lily’s colored-pencil box has 2 shades of red pencils and 5 shades of blue pencils. Joseph’s box has 1 shade of red pencils and 4 shades of blue pencils. Lily thinks that the ratio of red pencils to blue pencils is the same for both boxes, because they each have 3 more shades of blue pencils than shades of red pencils. Is the same ratio of shades of red pencils to shades of blue pencils maintained? Justify your response.
