How Many Parts Must a 100Ω Wire Be Cut Into to Achieve 1Ω Total Resistance?

[Karolis]

I really need you help to solve this problem. I've been trying to solve it for like an hour but still can't do it. So here it is.
100\Omega resistance wire is cut in equal parts, which are connected in parallel. They're total resistance is 1\Omega. In how many parts the wire is cut?

Thank you.

You seem you have forgotten to use the homework template, particularly sections two and three which ask you to write down the relevant equations and detail an attempted solution.
