Introduction

In mathematics, expressions are a fundamental concept that helps us represent and solve problems. Evaluating expressions is a crucial skill that involves simplifying and solving mathematical expressions. In this article, we will evaluate the expression 5+155 + \frac{1}{5} using a step-by-step approach.

Understanding the Expression

The given expression is 5+155 + \frac{1}{5}. This expression consists of two parts: a whole number 55 and a fraction 15\frac{1}{5}. To evaluate this expression, we need to add the whole number and the fraction.

Adding Whole Numbers and Fractions

When adding whole numbers and fractions, we need to follow a specific order of operations. The order of operations is:

  1. Add the whole numbers.
  2. Add the fractions.

Step 1: Add the Whole Numbers

In this step, we add the whole numbers 55 and 00 (since there is no whole number part in the fraction). The result is:

5 + 0 = 5

Step 2: Add the Fractions

In this step, we add the fractions 15\frac{1}{5} and 00 (since there is no fraction part in the whole number). To add fractions, we need to have the same denominator. In this case, the denominator is 55. Since the numerator of the fraction 15\frac{1}{5} is 11, we can add it to the whole number 55 without changing the denominator.

5 + 1/5 = 5 + 1/5

Step 3: Simplify the Expression

In this step, we simplify the expression by combining the whole number and the fraction. To do this, we need to convert the whole number to a fraction with the same denominator as the fraction. In this case, the denominator is 55. We can convert the whole number 55 to a fraction with the denominator 55 by multiplying it by 55\frac{5}{5}.

5 = 5/1 = 25/5

Now, we can add the fractions:

25/5 + 1/5 = 26/5

Conclusion

In conclusion, the expression 5+155 + \frac{1}{5} can be evaluated by following the order of operations and simplifying the expression. The result is 265\frac{26}{5}.

Introduction

In our previous article, we discussed how to evaluate expressions using a step-by-step approach. In this article, we will answer some frequently asked questions about evaluating expressions.

Q: What is an expression?

A: An expression is a mathematical statement that contains variables, constants, and mathematical operations. It is a way to represent a mathematical relationship between variables and constants.

Q: What is the order of operations?

A: The order of operations is a set of rules that tells us which operations to perform first when evaluating an expression. The order of operations is:

  1. Parentheses: Evaluate expressions inside parentheses first.
  2. Exponents: Evaluate any exponential expressions next.
  3. Multiplication and Division: Evaluate any multiplication and division operations from left to right.
  4. Addition and Subtraction: Finally, evaluate any addition and subtraction operations from left to right.

Q: How do I add fractions with different denominators?

A: To add fractions with different denominators, you need to find the least common multiple (LCM) of the denominators. The LCM is the smallest number that both denominators can divide into evenly. Once you have the LCM, you can convert both fractions to have the same denominator, and then add them.

Q: How do I simplify an expression?

A: To simplify an expression, you need to combine like terms and eliminate any unnecessary operations. Like terms are terms that have the same variable and exponent. You can combine like terms by adding or subtracting their coefficients.

Q: What is a variable?

A: A variable is a letter or symbol that represents a value that can change. Variables are used to represent unknown values or values that can change.

Q: What is a constant?

A: A constant is a value that does not change. Constants are used to represent values that are known or fixed.

Q: How do I evaluate an expression with parentheses?

A: To evaluate an expression with parentheses, you need to follow the order of operations. First, evaluate any expressions inside the parentheses. Then, evaluate any exponential expressions. Finally, evaluate any multiplication and division operations from left to right.

Q: How do I evaluate an expression with exponents?

A: To evaluate an expression with exponents, you need to follow the order of operations. First, evaluate any expressions inside parentheses. Then, evaluate any exponential expressions. Finally, evaluate any multiplication and division operations from left to right.
