#"Mass of fat" approx 25.3# #"pounds"#

Explanation:

According to Wikipedia, body fat percentage is defined as the total mass of fat divided by total body mass.

We are already provided with the individual's body fat percentage of #19.8%#, or #0.198#, and body mass of #128# pounds.

So let's find the weight of his body fat:

#Rightarrow 0.198 = frac("Mass of fat")(128 " pounds")#

#Rightarrow 0.198 times 128# #"pounds"# #=# #"Mass of fat"#

#Rightarrow "Mass of fat" = 25.344# #"pounds"#

Rounding to the nearest tenth:

#therefore "Mass of fat" approx 25.3# #"pounds"#
