Answer:

One serving of

  • a certain brand of yogurt contains 12 g of fat
  • the low-fat yogurt contains 38.75% less fat

Let x g be the amount of fat in low-fat yogurt. Then

12 g of fat - 100%

x g of fat - 100% - 38.75% = 61.26%

Write a proportion

\dfrac{12}{x}=\dfrac{100}{61.25}

Cross multuply

100\cdot x=12\cdot 61.25\\ \\100x=735\\ \\x=\dfrac{735}{100}=7.35

One serving of law-fat yogurt contains 7.35 g of fat.
