Question

Which proportion would you use to find 38% of 90?

90 = n
100 38


100 = 38
90 n


38 = n
100 90


38 = 90
100 n

Answer 1

you would take the 38 and place over 100 since its in percent (part over whole) and then you'd place the n over 90 (part you are looking for over whole)

so.....the 3rd one is correct
