Question 507941
{{{4/x = 12}}}
.
multiply both sides by 'x'
.
{{{ 4 = 12x }}}
.
divide both sides by 12
.
{{{ 4/12 = x }}}
or
{{{ 1/3 = x }}}
.
You also could solve this as a cross-multiplication.
.
{{{ 4/x = 12/1 }}}
.
{{{ 4*1 = 12*x }}}
.
{{{ 4 = 12x }}}
.
{{{ 12x = 4 }}}
.
{{{ x = 4/12 }}}
.
{{{ x = 1/3 }}}
.
Done.
