what is the fold with 100,000 to 9,000,000

Question

if there were 100,000 of something in the past, and now there was 9,000,000, what is the fold and how is it calculated?

Answer 1

If you had $100,000 Canadian to invest for a 3-5x profit (that can be validated), would you?

Does that make a bit more sense? Thanks for replyin

Answer 2

If by fold you mean manifold or degree of multiplication, then 9000000/100000=90.

Answer 3

You multiply them: 9000000 x 100000=90.
