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 represenation of the painting?

I think the answer is no. Is this right?

How did you come up with that?

I made a proportion 92/73=120/100 and I cross multiplied. I divided the cross products and it came up to a demical.

If you cross-multiplied, you should have done (92)(100) = (73)(12). 920 doesn't equal 8760, so you know the picture is out of proportion. Your answer is correct.

thanks

Yes, you are correct in thinking that the poster is not an accurate representation of the painting. To verify this, we can compare the dimensions of the painting to those of the poster.

The original painting, Starry Night by Van Gogh, measures 92 cm long by 73 cm high. On the other hand, the poster measures 120 cm long by 100 cm high.

Now, let's compare the aspect ratios of the painting and the poster. The aspect ratio is the ratio of the width to the height. For the painting, the aspect ratio is 92 cm / 73 cm ≈ 1.26. For the poster, the aspect ratio is 120 cm / 100 cm = 1.2.

Since the aspect ratios of the painting and the poster are not equal, it means that the proportions of the two are different. Therefore, the poster is not an accurate representation of the painting.
