Troy is building a pool that is proprtional to an olympic-sized pool the width of his pool will be 625 centimeters find the scale factor.

You will have to tell me the length and width of that big pool.

once you have the dimensions of the other pool set up the equation like this

big pool width/big pool length=625/x
for example purposes let the above equal this
w/l=625/x
to solve
l(625)=w(x)

l(625)/w=x

To find the scale factor, we need to compare the width of Troy's pool to the width of an Olympic-sized pool.

The width of Troy's pool is given as 625 centimeters. To determine the scale factor, we divide this width by the width of an Olympic-sized pool, also given as a certain value.

Unfortunately, the width of an Olympic-sized pool is not mentioned in the question. So, to find the scale factor, we need to know the width of an Olympic-sized pool. Once we have that information, we can divide Troy's pool's width by the Olympic-sized pool's width to get the scale factor.
