Solution:
We are given that 25 percent of n = 37 1/2 percent of m. So we have:
(25/100)n = (37.5/100)m
We can multiply both sides by 100:
25n = 37.5m
We can multiply both sides by 10:
250n = 375m
We can divide both sides by 25:
10n = 15m
2n = 3m
We can multiply both sides by 6 to get the 12n in the numerator of (12n)/m:
12n = 18m
Finally, divide both sides by m, obtaining the value of (12n)/m:
(12n)/m = 18
