Answer 1

Explanation:

In order to convert the person's mass to slugs, kilograms and pound-mass, we must know the equivalence between these units and lbs.

(a) 1 lb is equal to 0.031 slugs. So:

$169lb*\frac{0.031slugs}{1lb}=5.24slugs$

(b) 1 lb is equal to 0.45 kilograms.Thus:

$1lb*\frac{0.454kg}{1lb}=76.72kg$

(c) 1 lb is the international standard symbol for the pound-mass, that is, 169 lb are equal to 169 pound-mass.
