Answer:
What do I solve for? If it's the length of spool not used, then the answer is
9 11/24 yards of spool.
Explanation:
12 1/8 - 2 2/3=
12 - 2 + 1/8 - 2/3=
10 + (1/8 - 2/3)*24/24 = ==> multiply by 24 to get rid of denominator
10 + (24*1/8 - 24*2/3)/24 =
10 + (24/8 - 48/3)/24 =
10 + (3 - 16)/24 =
10*24/24+ (-13)/24 =
240/24 - 13/24=
(240-13)/24=
227/24=
(216+11)/24=
216/24 + 11/24=
9 + 11/24=9 11/24 yards of spool
