Answer:
The low fat version contains 7.35 grams of fat.
Explanation:
You have to consider that the content of fat in the regular version of the yogurt represents the 100 % of fat. Then you need to find the 38.75 %....
12 grams -------------- 100 %
x = ? --------------------- 38.75 %
So x = [(38.75 %) x 12 grams ] / 100 % ⇒ x = 4.65 grams.
Finally, you have to subtract 4.65 grams to the original 12 grams, to have the fat content in the low fat version. ⇒ 12 grams - 4.65 grams = 7.35 grams.
Summarizing, the low fat version has 7.35 grams of fat.
