A photo is 6 in wide and 3 in tall. If it is reduced to a height of 1 in, then how wide will it be?

1/3 * 6 = 2 inches

To find out the new width of the photo when its height is reduced to 1 inch, we can use the concept of proportional relationships.

The given photo is 6 inches wide and 3 inches tall. Let's label the original width as W and the original height as H.

According to the given information, we have:
W = 6 inches (original width)
H = 3 inches (original height)

Now, let's calculate the ratio of the original width to the original height:
Ratio = W/H

Ratio = 6 inches/3 inches
Ratio = 2 inches/inch

This means that for every 1 inch decrease in height, the width decreases by a factor of 2.

Since the height is reduced to 1 inch, we need to find the new width. Let's label the new width as W'.

Using the proportional relationship, we can set up the following equation:
W/H = W'/1

Substituting the values we have:
2 inches/inch = W'/1

Multiplying both sides of the equation by 1 inch gives:
2 inches = W'

Therefore, when the height is reduced to 1 inch, the width of the photo will be 2 inches.
