Question

Find the width of a photograph whose length is 24 inches and whose proportions are the same as a photograph that is 3 inches wide by 4 inches long

Answer 1

First, we can set up a proportion to find the ratio of the width to length for the photograph:

• 
  `\frac{\text{width}}{\text{length}} = (3)/(4)`

We can then use this ratio to find the width of the photograph with a length of 24 inches:

• 
  `\frac{\text{width}}{24\text{ in}} = (3)/(4)`

To solve for the width, we can cross-multiply:

• 
  `4\text{width} = 72\text{ in}`

Then divide by 4:

• 
  `\text{width} = \boxed{18\text{ in}}`

`\therefore` The width of the photograph is 18 inches.
