Answer:

The number is #72#

Explanation:

If #3/8# of the number is #27#, it means that #27# represents #3# parts.

Divide #27# by #3# to find #1# part.

#1# part = #27 div 3=9#

If #1/8# of a number is #9#, then #8/8# is the whole number which is #9xx8 =72#.

Using direct proportion.

#3/8 = 27/x" "(larr3 " parts")/(larr"full number"#

#x =(27xx8)/3#

#x=72#
