Question 984680
Let the 3rd number  = {{{ 100 }}}
{{{ .6*100 = 60 }}}
The 1st number is:
{{{ 100 + 60 = 160 }}}
---------------------
{{{ .2*100 = 20 }}}
The 2nd number is:
{{{ 100 + 20 = 120 }}}
---------------------
The 2nd number as a percentage of the 1st is:
{{{ ( 120/160 )*100 = (3/4)*100 }}}
{{{ (3/4)*100 = 75 }}}
75%
