<PRE><B>Question 584669</B>
A skirt requires 2-1/3 yards of material.
 How many skirts can be cut from 42 yards?
:
Convert 2 1/3 yds: 2*3 + 1 = {{{7/3}}}
:
{{{42/(7/3)}}}
:
invert the dividing fraction and multiply
42 * {{{3/7}}} = {{{126/7}}} = 18 skirts from 24 yds of material
:
Check this
18 * 7/3
Cancel 3 into 18 and you have;
6 * 7 = 42</PRE>
