Question

I have tried multiple approaches on this problem and I cannot get the correct answer, maybe someone can explain it to me.
Question:
What is the density of a substance in pennyweights per peck that has a volume of 0.334 hogsheads and a mass of 54.9kg.
1 pennyweight= 1.55 grams
1 hogshead= 238.5 liters
1 peck= 9.091 liters.
What is the answer in pw/pk? thanks

Answer 1

(54.9/0.334) x 1000 x (1/1.55) x (1/238.5) x 9.091

(kilograms/hogshead)x (grams/kilogram)x (pennyweight/gram) x

(hogsheads/liter) x (liters/peck)

Units all cancell out except for pennyweights/peck

Crunch the number see what you get.
