Question

What is the yarn number* of a 60 grain/yd sliver in cotton hanks/lb?

Answer 1

0.138 hanks/lb

Explanation:

Given:

Silver = 60 grain/yd

Now,

1 hank = 840 yd

or

1 yd =
`\frac{\textup{1}}{\textup{840}}` hank

And,

1 lb = 7000 grain.

or

1 grain =
`\frac{\textup{1}}{\textup{7000}}` lb

Thus,

60 grain/yd =
`(60*(1)/(7000))/(1*(1)/(840))` lb/hanks

or

60 grain/yd = 7.2 lb/ hanks

or

`\frac{\textup{1}}{\textup{7.2}}` hanks/lb

or

0.138 hanks/lb
