Homework Statement
If m is an odd integer and n divides m, then n is an odd integer.
Homework Equations
Odd integers can be written in the form m=2k+1.
Since n divides m, there exists an integer p such that m=np
The Attempt at a Solution
We will assume that m is an odd integer and that n divides m. We will show that n is an odd integer. Since m is an odd integer, there exists an integer k such that m=2k+1. Since n divides m, there exists an integer p such that m=np.
I don't know where to go from here to arrive at n is equal to 2*an integer +1. Do I need to use cases?
