Let the numbers m, n, p, and s be defined as:

m = 0.1212121212 ...

n = 0.1221221221 ...

p = 0.1122112211 ...

s = 0.1112221112 ...

Which choice shows the correct ordering of these numbers?

You take the first number and if the first number is bigger that all the other first numbers than that number is bigger you do this down the line 2nd number 3rd number etc. it also works for the smallest number too

If it's G2L, you'd do N, M, P, S, if it's L2G, you'd do S, P, M, N.
