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.
