The number is #20#

#15/100 xx 20=3#

You can use direct proportion for any percent calculation.

Compare each number with its percent.

#3# is #15%# of what number? Let the number be #x#

So #3# represents #15%# and #x# represents #100%#

#x/100 =3/15" "(larr "number")/(larr "percent")#

Multiply by #100# to isolate #x#

#x = (3xx100)/15#

#x=20#

Check: #15/100 xx20 =3#
