Question 578067
Let {{{ x }}} = gallons of water to be added
{{{ 1 / ( 1 + x ) = .45 }}}
{{{ 1 = .45*( 1 + x ) }}}
{{{ 1 = .45 + .45x }}}
{{{ .45x = .55 }}}
{{{ .09x = .11 }}}
{{{ x = .11/.09 }}}
{{{ x = 1.222 }}}
1.222 gallons of water must be added
check:
{{{ 1 / ( 1 + x ) = .45 }}}
{{{ 1 / ( 1 + 1.222 ) = .45 }}}
{{{ 1 / 2.222 = .45 }}}
{{{ 1 = .45*2.222 }}}
{{{ 1 = .9999 }}}
OK - error due to rounding off
