If 80% of M is equal to 50% of N and N≠0, what is N M equal to?
asambeis [7]

Answer:

0.625N

Step-by-step explanation:

                                        0.50N

0.80M = 0.50N, so M = ------------

                                          0.80

and so:

                0.50N

N*M = N*------------ = (5/8)N, or 0.625N

                   0.80
