If 80% of M is equal to 50% of N and N≠0, what is N/M equal to?

1 answer:

5 0

Whatever% of anything is just (whatever/100) * anything.

thus, what is 80% of M, well is just (80/100) * M,

what is 50% of N? well is just (50/100) * N.

we know they're both equal, thus

$\bf \cfrac{80}{100}M=\cfrac{50}{100}N\implies \cfrac{8M}{10}=\cfrac{5N}{10}\implies \cfrac{4M}{5}=\cfrac{N}{2}
\\\\\\
\cfrac{4\cdot 2}{5}=\cfrac{N}{M}\implies \cfrac{8}{5}=\cfrac{N}{M}$
