A photo that is 4 in wide and 6 in high is enlarged to a poster that is 3ft wide and 4 1/2 ft high what is the ratio of the width of the photo to the width of the poster

Respuesta :

1:9 would be the ratio

Answer:

Required ratio in the simplest form = 1 : 9

Step-by-step explanation:

Width of photo = 4 inches

Height of the photo = 6 inches

Width of the poster = 3 feet

Now, 1 feet = 12 inches

So, Width of the poster = 3 × 12 = 36 inches

Height of the poster = 4.5 feet

                                  = 54 inches

We need to find the ratio of the width of the photo to the width of the poster

⇒ Required Ratio = 4 : 36

⇒ Required ratio in the simplest form = 1 : 9
