#1/3 xx x =72#

It turns out that there are #216# bagels.

A common error that students make is to write #1/3 = 72#

This is obviously not true!!

What they should write is that #1/3# of some number #=72#

Let that number be #x#

#1/3 xx x = 72#

#(3xx1)/3 =3xx72" "larr# multiply both sides by #3#

#x = 216#

#216#

Let the total bagels in the bakery be# x#

#:.1/3x=72#

#:.x=72/(1/3)#

#:.x=72/1xx3/1#

#:.x=216#
