If n and d are positive integers such that n is a multiple of d, how many positive
multiples of d are less than or equal to n?

n/d

d/n
d(n+1)
d/n+1

Thanks I got it now. It's n/d

if n= 100 and d =25, then n/d =4 equal to the multiples of 25 under or = 100: 25,50,75, 100

12/3 = 4, multiples: 3, 6,9, 12
