Question

A photo that is 4 in. wide and 6 in. high is enlarged to a

poster that is 3 ft wide and 4 ft high. What is the ratio
of the width of the photo to the width of the poster?

Answer 1

The ratio of the width of the photo to the width of the poster is 1:9 or 1/9

Explanation:

1. Let's review the information provided to us to answer the question correctly:

Photo = 4 in. wide and 6 in. high

Poster = 3 ft wide and 4 ft high

2. What is the ratio of the width of the photo to the width of the poster?

Let's recall that 1 foot = 12 inches

Let's convert the width of the poster to inches, this way:

3 feet = 3 * 12 inches

3 feet = 36 inches

The width of the poster is 36 inches

Now, we calculate the radio, as follows:

Ratio = Width of the photo in inches/Width of the poster in inches

Ratio = 4/36 = 1/9 (Simplifying)

The ratio of the width of the photo to the width of the poster is 1:9 or 1/9
