Question 965913
A toy Company has designed a new dress for one of it's dolls. each dress requires 3/4 yard of fabric and 2/3 foot of ribbon. how many yards of fabric are needed for every 1 foot of ribbon.
<pre>
{{{red((matrix(4,1,
3/4,yd,of,fabric)))}}}{{{matrix(1,2,is,to)}}}{{{green((matrix(4,1,
2/3,ft,of,ribbon)))}}}{{{as}}}{{{green((matrix(4,1,
N,yd,of,fabric)))}}}{{{matrix(1,2,is,to)}}}{{{red((matrix(4,1,
1,ft,of,ribbon)))}}}

The product of the MEANS (the green quantities) equals the product
of the EXTREMES (the red quantities:

{{{green(expr(2/3)N)}}}{{{""=""}}}{{{red(expr(3/4)*1)}}}

{{{green(expr(2/3)N)}}}{{{""=""}}}{{{red(expr(3/4))}}}

So divide {{{3/4}}}{{{"÷"}}}{{{2/3}}}{{{""=""}}}{{{3/4}}}{{{"×"}}}{{{3/2}}}{{{""=""}}}{{{9/8}}}{{{""=""}}}{{{1&1/8}}}

So,

{{{red((matrix(4,1,
3/4,yd,of,fabric)))}}}{{{matrix(1,2,is,to)}}}{{{green((matrix(4,1,
2/3,ft,of,ribbon)))}}}{{{as}}}{{{green((matrix(4,1,
1&1/8,yd,of,fabric)))}}}{{{matrix(1,2,is,to)}}}{{{red((matrix(4,1,
1,ft,of,ribbon)))}}}
