I'm struggling to understand binary relations in discrete mathematics.Can anyone solve these for me?
1.
Let A be {5,10,15,20,25,30,35,40,45,50,55}
aRb if a's and b's smallest prime divisors are the same.
Define the equivalence classes.
2.
Let A be {2,6,10,18,25,50,60,75,150}
a≼b if a|b
Define the set of the maximum elements of the ≼ by listing them.
Sorry for the grammatical mistakes.
