Introduction

When it comes to making punch, the amount of grape juice needed is crucial in determining the number of servings that can be made. In this scenario, Ryah has 4 cups of grape juice, and we need to find out how many ${$ \frac{1}{2}$}$-cup servings of punch can be made from this amount. This problem involves basic division and fraction operations, which are essential skills in mathematics.

Understanding the Problem

To solve this problem, we need to understand the concept of fractions and how they relate to division. A fraction represents a part of a whole, and in this case, we have ${$ \frac{1}{2}$}$ cup servings of punch. This means that each serving is half of a cup. We need to find out how many of these half-cup servings can be made from 4 cups of grape juice.

Calculating the Number of Servings

To calculate the number of servings, we need to divide the total amount of grape juice (4 cups) by the amount of grape juice needed for each serving ( ${$ \frac{1}{2}$}$ cup). This can be represented as:

4 ÷ ${$ \frac{1}{2}$]

To divide a whole number by a fraction, we can multiply the whole number by the reciprocal of the fraction. The reciprocal of [ $\frac{1}{2}\$] is \[$ \frac{2}{1}$]. So, we can rewrite the division as:

4 × [$\frac{2}{1}$]

Multiplying Whole Numbers and Fractions

When multiplying a whole number by a fraction, we multiply the whole number by the numerator (the top number) and keep the denominator (the bottom number) the same. In this case, we multiply 4 by 2:

4 × 2 = 8

So, the result of the multiplication is 8. However, we need to keep the denominator [$\frac{1}{1}$] as it is, which is the same as 1. Therefore, the result of the multiplication is:

8 ÷ 1 = 8

Conclusion

In conclusion, Ryah can make 8 [ $\frac{1}{2}\$}$ -cup servings of punch from 4 cups of grape juice. This problem involves basic division and fraction operations, which are essential skills in mathematics. By understanding the concept of fractions and how they relate to division, we can solve problems like this and make informed decisions in real-life situations.

Introduction

In our previous article, we solved the problem of how many ${$ \frac{1}{2}$}$-cup servings of punch can be made from 4 cups of grape juice. We used the concept of fractions and division to find the solution. In this article, we will provide a Q&A section to help you understand the problem and its solution better.

Q&A

Q: What is the problem asking for?

A: The problem is asking for the number of ${$ \frac{1}{2}$}$-cup servings of punch that can be made from 4 cups of grape juice.

Q: What is the key concept in solving this problem?

A: The key concept in solving this problem is the concept of fractions and division. We need to divide the total amount of grape juice (4 cups) by the amount of grape juice needed for each serving ( ${$ \frac{1}{2}$}$ cup).

Q: How do we divide a whole number by a fraction?

A: To divide a whole number by a fraction, we can multiply the whole number by the reciprocal of the fraction. The reciprocal of ${$ \frac{1}{2}$] is [$\frac{2}{1}$].

Q: What is the result of multiplying 4 by [$\frac{2}{1}$]?
