Introduction

In mathematics, multiplication is a fundamental operation that involves finding the product of two or more numbers. When dealing with decimals, it's essential to understand how to multiply them to obtain a specific product range. In this discussion, we will focus on selecting decimals that, when multiplied by 8, result in a product that falls between 4 and 6.

Understanding the Problem

To solve this problem, we need to find the decimals that satisfy the given condition. We are looking for decimals that, when multiplied by 8, result in a product between 4 and 6. This means we need to find the range of decimals that, when multiplied by 8, will give us a value between 4 and 6.

Calculating the Product Range

To find the product range, we need to multiply the given range by 8. The given range is between 4 and 6. When we multiply 4 by 8, we get 32. When we multiply 6 by 8, we get 48. Therefore, the product range is between 32 and 48.

Selecting Decimals

Now that we have the product range, we can select the decimals that satisfy the given condition. We need to find the decimals that, when multiplied by 8, result in a product between 32 and 48.

Option A: 0.49

When we multiply 0.49 by 8, we get 3.92. This product is less than 32, so option A is not a valid choice.

Option B: 0.52

When we multiply 0.52 by 8, we get 4.16. This product is between 32 and 48, so option B is a valid choice.

Option C: 0.66

When we multiply 0.66 by 8, we get 5.28. This product is between 32 and 48, so option C is a valid choice.

Option D: 0.78

When we multiply 0.78 by 8, we get 6.24. This product is greater than 48, so option D is not a valid choice.

Option E: 0.8

When we multiply 0.8 by 8, we get 6.4. This product is greater than 48, so option E is not a valid choice.

Conclusion

In conclusion, the decimals that, when multiplied by 8, result in a product between 4 and 6 are 0.52 and 0.66. These decimals satisfy the given condition and fall within the product range of 32 and 48.
