**Rounding Numbers to the Nearest 5: A Guide to Mathematics**

Introduction

Rounding numbers is an essential skill in mathematics, and it's used in various real-life applications. In this article, we'll focus on rounding numbers to the nearest 5, which is a crucial concept in mathematics. We'll explore the rules and examples of rounding numbers to the nearest 5, and we'll also provide practice exercises to help you master this skill.

What is Rounding to the Nearest 5?

Rounding a number to the nearest 5 involves finding the closest multiple of 5 to the given number. This means that if the number ends in 0 or 5, it's already a multiple of 5, and you don't need to round it. However, if the number ends in 1, 2, 3, or 4, you need to round it to the nearest multiple of 5.

Rules for Rounding to the Nearest 5

Here are the rules for rounding numbers to the nearest 5:

If the number ends in 0 or 5, it's already a multiple of 5, and you don't need to round it.
If the number ends in 1, round up to the next multiple of 5.
If the number ends in 2, round up to the next multiple of 5.
If the number ends in 3, round up to the next multiple of 5.
If the number ends in 4, round up to the next multiple of 5.

Examples of Rounding to the Nearest 5

Let's look at some examples of rounding numbers to the nearest 5:

192: Since 192 ends in 2, we need to round up to the next multiple of 5, which is 195.
100: Since 100 ends in 0, it's already a multiple of 5, and we don't need to round it.

Practice Exercises

Here are some practice exercises to help you master the skill of rounding numbers to the nearest 5:

Round 145 to the nearest 5.
Round 275 to the nearest 5.
Round 420 to the nearest 5.
Round 625 to the nearest 5.

Answer Key

Here are the answers to the practice exercises:

145: 145 (since it ends in 5, it's already a multiple of 5)
275: 280 (since it ends in 5, it's already a multiple of 5)
420: 420 (since it ends in 0, it's already a multiple of 5)
625: 625 (since it ends in 5, it's already a multiple of 5)

Conclusion

Rounding numbers to the nearest 5 is an essential skill in mathematics, and it's used in various real-life applications. By following the rules and examples provided in this article, you'll be able to master this skill and become more confident in your math abilities. Remember to practice regularly to improve your skills and become proficient in rounding numbers to the nearest 5.
