scale factor problem

[suzb]

Im sorry if I DO something wrong, It's my first time posting:

I have done some simple scaling and ratio work but I found this in my GED practice test and I'm stumped.

there is a drawing of 2 prism models: Prism 1 has a right angle base and a legth of 50mm, Prism 2 has equilateral triangles as bases and a length of 50mm (Some of this info is probably not relevant) The question is:

"a company will make scale models of both prisms. The model of prism 1 will use a scale factor of 2.5. The model of prism 2 will have the length of 75 mm. Complete the porportion that can be used to find the length , "L" of prism model 1. Then find the scale factor"K" that can be used to make the model of prism 2"

____=____
L

K=______

And I am supposed to fill in the blanks

IF anybody can help me I'll be very grateful.

No worries! Here's a link to the forum guidelines summary.

You've worked basic proportion exercises; you already made a start, on this one, yes?

Can you explain what you've thought about? Or, is there part of the exercise statement that has you puzzled?

Also, I think that the drawing is not of the models; those are the prisms that are being modeled. Otherwise, the length L of prism model 1 is 50mm.

If you're totally stuck, then simply tell us what you think proportion means, and we'll go from there, instead.

Cheers :cool:
