Would someone please be kind enough to explain steps for this one. Thank you.
If m and n are positive integers and m is 250% of n, what percent of m is 2n?

Math Help Please  Reiny, Monday, February 27, 2012 at 8:29am
m = 2.5n
2m = 5n
n = (2/5)m
2n = (4/5)m
4/5 = .8 = 80%
e.g.
let n = 10, then m = 25
then 2n = 20
percentage of 25 is 20 > 20/25 = .8 = 80%
