2. the ratio of creamy to crunchy peanut butter jars on a grocery store shelf is 5 to 3. there are 18 jars of crunchy peanut butter. what is the total number of jars of peanut butter on the shelf?
Answer
Explanation:
Step1: Set up proportion
Let the number of creamy peanut - butter jars be $x$. The ratio of creamy to crunchy is $5:3$, so $\frac{x}{18}=\frac{5}{3}$.
Step2: Solve for $x$
Cross - multiply: $3x = 18\times5$. Then $3x=90$, and $x = 30$.
Step3: Calculate total number of jars
The total number of jars is the sum of creamy and crunchy jars. Total $=30 + 18=48$.
Answer:
48
