Question 340340
Given: {{{((2 + 1/6)/( 3 + 1/3))*((6 + 1/4)/(4 + 1/3))}}}


Mentally multiply the fraction on the left by 6/6 and the fraction on the right by 12/12 to get:

{{{((12 + 1)/(18 + 2))*((72 + 3)/(48 + 4))}}}


Simplify
{{{(13/20)*(75/52)}}}
{{{(13/52)*(75/20)}}}
{{{(1/4)*(5(15)/5(4))}}}
{{{(1/4)*(15/4)}}}
{{{(15/16)}}}
