If the thickness of the pipe wall is inch=inch,
we have to add to the inner diameter twice that thickness to get the outside diameter, which is
inch=inch=inch
For the silk problem, we need to get all those numbers as fractions of a yard,
rather than mixed numbers with mixed units.
6 inches = (1/2) foot and 1 foot = 1/3 yard, so
6 inches = (1/2) of (1/3) of a yard or of a yard
3yards 6 inches = 3 yards + 1/6 yard =
Let's add all those yards of fabric:
Now we need a common denominator,
and is the least common denominator we could use
It was a total of 12 yards.

add 7 5/8 and 5 5/8.
then from their sum subtract 11 5/16.
