The current population of Summerfield is 16,359 people, which is 90% larger than when David moved there. What was the population of Summerfield back then?

I need some help, there's this question on IXL (It's a website that has math problems for you to answer) that I couldn't answer. What I think is we should add 100% and 90% which will be 190%, and then we will divide 1.9 to 16,359. And the answer will be 0.00011614, but the thing is, it doesn't make that much sense to me, does it make sense?

  1. You have it backward. If the original population was x, then

    1.9x = 16359
    x = 16359/1.9 = 8610
