    $2\frac35$

=  $2+\frac35$                 Multiply the  2  by  $\frac55$ .

                                ( $\frac55$ = 1 , so this does not change the value of our expression. )

=  $\frac55\,*\,2\,+\,\frac35$

=  $\frac{5*2}{5}\,+\,\frac35$

=  $\frac{10}{5}\,+\,\frac35$

                               10 cookies + 3 cookies = 13 cookies, so 10 fifths + 3 fifths = 13 fifths.

=  $\frac{13}{5}$
