If you and three friends each ate \( \frac{1}{3} \) of a bag of candy, that means you all together shared \( 4 \) people eating \( \frac{1}{3} \) of a bag each.
To find out how many bags that is in total, you can multiply the number of people by the amount of candy each person ate:
\[ 4 \times \frac{1}{3} = \frac{4}{3} \text{ bags} \]
So altogether, you ate \( \frac{4}{3} \) bags of candy, which is equivalent to 1 and \( \frac{1}{3} \) bags, or approximately 1.33 bags.
Based on the options given, none of them seem to properly express this result clearly or accurately. The closest indication provided is:
1 \( \frac{1}{3} \) bags
This seems to represent the total amount accurately, even if the format is not clearly stated.
For clarification, if by "each of you ate 13" you meant each of you ate \( \frac{1}{3} \) of a bag, then \( \frac{4}{3} \) bags was correct. Если вы имеете в виду что-то другое, пожалуйста, дайте мне знать, чтобы я мог помочь правильно!
