If m and n are positive integers, and m=2n and k=5m, then -
If m and n are positive integers, and m=2n and k=5m, then -
Answer/Solution
m/2 is a factor of k.
Steps/Work
m=2n --> m is even.
k=5m --> m is factor of k, thus m/2 = integer must also be a factor of k.
Answer: C.
k=5m --> m is factor of k, thus m/2 = integer must also be a factor of k.
Answer: C.
