A package contains 1.33 lb of ground round. If there’s 29% fat, how many grams of fat are in the round?
OlgaM077 [116]

The answer is: 175 grams of fat are in the round.

m(ground round) = 1.33 ib.

First convert ib (pounds) to g (grams):

1 pound (lb) is equal to 453.592 grams (g).  

m(ground round) = 1.33 ib · 453.592 g/ib.

m(ground round) = 603.28 g.

ω(fat) = 29% ÷ 100%.

ω(fat) = 0.29; mass percentage of fat.

m(fat) = ω(fat) · m(ground round).

m(fat) = 0.29 · 603.28 g.

m(fat) = 175 g; mass of fat.
