Tim has a picture frame that is 30 centimeters long and 24 centimeters wide he wants to make a picture frame that is similar in shape but is 18 centimeters long how wide should the second picture frame be

Solve this proportion.

30/24 = 18/x

To find out how wide the second picture frame should be, we need to determine the ratio of lengths between the two frames.

The ratio of lengths is found by dividing the length of the desired second frame by the length of the original frame:
Ratio of Lengths = Desired Length / Original Length

In this case, the desired length is 18 centimeters, and the original length is 30 centimeters:
Ratio of Lengths = 18 cm / 30 cm

Simplifying the ratio:
Ratio of Lengths = 3/5

Now, we can apply this ratio to find the width of the second frame.

The width of the second frame is found by multiplying the ratio of lengths by the original width:
Width of Second Frame = Ratio of Lengths * Original Width

In this case, the original width is 24 centimeters:
Width of Second Frame = (3/5) * 24 cm

Calculating the width of the second frame:
Width of Second Frame = 14.4 cm

Therefore, the second picture frame should be 14.4 centimeters wide to maintain the similar shape.
