Introduction

In this article, we will explore the concept of estimating expressions, which is a crucial skill in mathematics. Estimating expressions involves approximating the value of an expression using simple arithmetic operations. This skill is essential in real-life situations, such as calculating the cost of items, determining the time required to complete a task, or estimating the value of a quantity. In this article, we will focus on estimating two expressions: $\frac{1}{8}+\frac{2}{5}$ and $\frac{13}{14}-\frac{1}{10}$.

Estimating the First Expression

To estimate the expression $\frac{1}{8}+\frac{2}{5}$, we need to find the closest decimal approximation of each fraction. The closest decimal approximation of $\frac{1}{8}$ is 0.125, and the closest decimal approximation of $\frac{2}{5}$ is 0.4.

# Expression 1: 1/8 + 2/5
# Estimate: 0.125 + 0.4

Now, let's add the two decimal approximations: 0.125 + 0.4 = 0.525. Therefore, the estimate for the expression $\frac{1}{8}+\frac{2}{5}$ is 0.525.

Estimating the Second Expression

To estimate the expression $\frac{13}{14}-\frac{1}{10}$, we need to find the closest decimal approximation of each fraction. The closest decimal approximation of $\frac{13}{14}$ is 0.929, and the closest decimal approximation of $\frac{1}{10}$ is 0.1.

# Expression 2: 13/14 - 1/10
# Estimate: 0.929 - 0.1

Now, let's subtract the two decimal approximations: 0.929 - 0.1 = 0.829. Therefore, the estimate for the expression $\frac{13}{14}-\frac{1}{10}$ is 0.829.

Conclusion

In conclusion, estimating expressions is a crucial skill in mathematics that involves approximating the value of an expression using simple arithmetic operations. In this article, we estimated two expressions: $\frac{1}{8}+\frac{2}{5}$ and $\frac{13}{14}-\frac{1}{10}$. We found that the estimate for the expression $\frac{1}{8}+\frac{2}{5}$ is 0.525, and the estimate for the expression $\frac{13}{14}-\frac{1}{10}$ is 0.829. These estimates can be used in real-life situations to make informed decisions or to calculate the cost of items.
