Answer:
One serving of law-fat yogurt contains 7.35 g of fat.
Explanation:
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
![(12)/(x)=(100)/(61.25)](https://img.qammunity.org/2020/formulas/mathematics/middle-school/mnuonujor9cwrt93hzltbz6sjkw2vfybqr.png)
Cross multuply
![100\cdot x=12\cdot 61.25\\ \\100x=735\\ \\x=(735)/(100)=7.35](https://img.qammunity.org/2020/formulas/mathematics/middle-school/ravhsvksgjn18vw66mj0bx419mff0bcb1h.png)
