Question

at the beginning of the month, there were 80 ounces of peanut butter in the pantry. now, there is \\(\frac{1}{3}\\) less than that. which expression can be used to find how many ounces of peanut butter are in the pantry now? (lesson 4-4)
\\(\bigcirc\\) a) \\(\frac{2}{3} \cdot 80\\)
\\(\bigcirc\\) b) \\(\frac{1}{3} \cdot 80\\)
\\(\bigcirc\\) c) \\(80 - \frac{1}{3}\\)
\\(\bigcirc\\) d) \\(\left(1 + \frac{1}{3}\
ight) \cdot 80\\)

Explanation:

Step1: Analyze the remaining fraction

If there is $\frac{1}{3}$ less than the original amount, the remaining fraction of peanut butter is $1 - \frac{1}{3}=\frac{2}{3}$.

Step2: Determine the expression

To find the current amount, we multiply the original amount (80 ounces) by the remaining fraction ($\frac{2}{3}$). So the expression is $\frac{2}{3}\cdot80$.

Answer:

A) $\frac{2}{3}\cdot80$
