Question 949928
SEE BELOW FOR "BETTER UNDERSTANDING..."


Original fraction, {{{n/d}}}.
'
New fraction, {{{(1.6)n/(0.6*d)}}}
{{{(1.6/0.6)(n/d)}}}
{{{(16/6)(n/d)}}}
{{{highlight((8/3)(n/d))}}}
OR
{{{highlight((2&2/3)(n/d))}}}


Factor of 1 would be 100% of original.
The factor obtained means about 267% of original.


The new fraction can be expressed as {{{highlight((8n)/(3d))}}}.



BETTER UNDERSTANDING HERE:
May have misunderstood your description.  If denominator decreased by 60%, then {{{d-(6/10)d=0.4d}}}
which would mean
{{{1.6n)/(0.4d)}}}
{{{(16/4)(n/d)}}}
{{{highlight(4(n/d))}}}, the new fraction.
