Van Gogh’s painting Starry Night measures 92 cm long by 73 cm high. You buy a poster that shows an enlargement of the painting. The poster measures 120 cm long by 100 cm high. Is the poster an accurate representation of the painting? (Hint: Is the poster similar to the painting?)

To be proportional, does 73/92 = 100/120?

To determine if the poster is an accurate representation of the painting, we need to compare the proportions of the poster to those of the original painting.

First, let’s calculate the aspect ratio of the original painting. The aspect ratio is the ratio of the width to the height. For the painting Starry Night, the length is 92 cm and the height is 73 cm. So the aspect ratio of the original painting is 92/73 ≈ 1.26.

Now, let’s calculate the aspect ratio of the poster. The length is 120 cm and the height is 100 cm. So the aspect ratio of the poster is 120/100 = 1.2.

Since the aspect ratio of the poster (1.2) is not the same as the aspect ratio of the painting (1.26), we can conclude that the poster is not an accurate representation of the painting. The proportions of the poster are not similar to the proportions of the original painting.
