Introduction

Beth is presented with a set of number cards and is tasked with creating a decimal that falls within a specific range. The target range is between $\frac{46}{100}$ and $\frac{53}{100}$ . In this article, we will explore the possible combinations of number cards that Beth can use to create a decimal that meets this criterion.

Understanding the Decimal Range

Before we dive into the possible combinations of number cards, let's understand the decimal range that Beth needs to target. The lower bound of the range is $\frac{46}{100}$ , which is equivalent to 0.46. The upper bound of the range is $\frac{53}{100}$ , which is equivalent to 0.53. Therefore, Beth needs to create a decimal that is greater than 0.46 and less than 0.53.

Number Cards and Their Possible Combinations

Let's assume that Beth has the following number cards:

We will now explore the possible combinations of number cards that Beth can use to create a decimal that falls within the target range.
