Question 945407
Let the 1st girl's number = {{{ a }}}
Let the 2nd girl's number = {{{ b }}}
-------------------------------
(1) {{{ ( ( a + b ) / 2 ) / 3 }}}
(2) {{{ ( 3*( a + b ) ) / 2 }}}
-------------------------
(1) {{{ ( a + b ) / 6 }}}
and
(2) {{{ ( 3/2 )*( a + b ) }}}
-----------------------
(1) divided by (2) is:
{{{ ( ( a + b ) / 6 ) / ( ( 3/2 )*( a + b ) ) }}}
Divide top and bottom by {{{ a + b }}}
{{{ ( 1/6 ) / ( 3/2 ) }}}
{{{ ( 1/6 )*( 2/3 ) }}}
{{{ 2/18 = 1/9 }}}
The answer is (b)
