gi. Reducing the fractional part of a quart, we have 18 qt.
pt. 1.7 = gi. (.2 qt. .2 X 8 = l.G gi. 1.6 ; + .1 = gi. 1.7 gi.).
Then, we can reduce 18 qt. to gallons (18 -r- 4 = 4 gal. and
2 = qt.) 4 gal. 2 qt. 1.7 gi. Ans.
The answer may be obtained in another and much easier
way by reducing all to gills, multiplying by 4.7, and then
changing back to quarts and pints. Thus,
3qt.
X 2 pt. 3 qt. 1 pt. 3 gi. = 31 gi.
6pt.
