Troy is building a pool that is proprtional to an olympicsized 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
