This is now folded with the remaining counts 20, in a similar operation—

26⅔ × 20
= 113⁄7 resultant counts or × 3 = 342⁄7 average counts.
26⅔ + 20

This result can be verified by the original method—

80 ÷ 80= 1
80 ÷ 40= 2
80 ÷ 20= 4
80 hanks= 7 lb.

80 ÷ 7 = 113⁄7 × 3 = 342⁄7 average.

Example 36.—Give all useful particulars for the following combination of yarns in a garment—

1 - 2/42 wor.@5/6per lb.
1 - 12's cotton@3/6per lb.
1 - 80/2 silk@15/-per lb.

Bring the worsted to cotton counts and the three yarns will then be in a like denomination—

21 × 560
= 14's cotton.
840

Arranging these for the resultant counts, price and weight relationships—
