(a)
Interpretation: The body fat in pounds should be calculated with the body mass is
Concept Introduction: Various units are used to express mass, volume, length etc. These units can convert into each other with the help of equality. The fraction of any equality is called conversion factors. In conversion factor, equalities are written as numerator and denominator.
(b)
Interpretation: The mass of fat removed must be calculated in pounds if the body fat density is
Concept Introduction: Density is the physical quantity that represents the ratio of mass and volume. The mathematical expression of density can be written as:
