Mandy is enlarging a photo that is 3 in. wide and 4.5 in long. if she wants the width of the enlargement to be 10 in, what will be the length??

15 in long

4.5(10/3) = _______ inches

To find the length of the enlargement, we can use proportions.

First, let's set up the proportion:

(original width) / (original length) = (enlarged width) / (enlarged length)

We know that the original width is 3 inches, the original length is 4.5 inches, and the enlarged width is 10 inches.

So, we can plug in the known values into the proportion:

3 / 4.5 = 10 / x

Now, we can cross-multiply and solve for x, which represents the length of the enlargement:

3x = 4.5 * 10

Multiplying 4.5 by 10, we get:

3x = 45

Now divide both sides of the equation by 3:

x = 45 / 3

Simplifying, we have:

x = 15

Therefore, the length of the enlargement will be 15 inches.
