Question 1096455
Let {{{ x }}} and {{{ y }}} = the original dimensions
{{{ 1.5x }}} and {{{ 1.5y }}} = new dimensions
-------------------------------------------
{{{ x*y }}} = original area
and
{{{ ( 1.5x )*( 1.5y ) = 2.25*x*y }}}
and
{{{ ( 2.25*x*y ) / ( x*y ) = 2.25 }}}
{{{ 2.25*100 = 225 }}}
225%
---------------------------------
{{{ 252/12 = 21 }}}
{{{ 252/14 = 18 }}}
{{{ 252/18 = 14 }}}
{{{ 252/21 = 12 }}}
{{{ 252/7 = 36 }}}
{{{ 252 - 5 = 247 }}}
247 increased by 5 is smallest number
--------------------------------------
Let {{{ x }}} = number of words on the test
{{{ ( x - 8 ) / x = .68 }}}
{{{ x - 8 = .68x }}}
{{{ .32x = 8 }}}
{{{ x = 25 }}}
There were 25 words on the test
--------------------------------
check:
{{{ ( 25 - 8 ) / 25 = .68 }}}
{{{ 17 / 25 = .68 }}}
{{{ .68 = .68 }}}
OK
