Question

Jane enlarged the photograph at the right to a poster. The size of the poster is 105 inches by 175 inches. Is the ratio of the poster's length and width equivalent to the ratio of the photograph's length and width? Explain your reasoning.​

Answer 1

The ratio dimensions of the poster i.e. 3 : 5, may or may not match the ratio of the photograph's length and width.

Explanation:

As the photograph is enlarged the length and width of the photograph will be enlarged in the same ratio.

Now, the dimensions of the poster are 105 inches by 175 inches.

That means the ratio of length and the width is 105 : 175 = 15 : 25 = 3 : 5

But it is given that Jane enlarged the photograph at the right to the poster.

Therefore, the ratio dimensions of the poster i.e. 3 : 5, may or may not match the ratio of the photograph's length and width. (Answer)
