Question 719178

if you have this:

{{{9rs *1/3tw }}}...you can write whole number as a fraction if you put {{{1}}} for denominator, so

{{{(9rs/1) *(1/3tw) }}}...multiply nominator by nominator and denominator by denominator

{{{(9rs*1)/(1*3tw) }}}

{{{(9rs)/(3tw) }}}...reduce

{{{(cross(9)3rs)/(cross(3)1tw) }}}

{{{(3rs)/(tw) }}}


or, if you have this:

{{{9rs *(1/3)tw }}}

{{{(9rs)/1 *(tw/3) }}}

{{{(9rstw)/3 }}}

{{{(cross(9)rstw)/cross(3) }}}

{{{3rstw }}}
