What is it?

Multiples of 5 are the numbers you get when you multiply 5 by any whole number (like 1, 2, 3, and so on). They are essentially numbers that can be divided by 5 without leaving any remainder. Think of them as jumping 5 steps at a time on a number line.

Simple Example

Quick Example

Imagine you are buying samosas, and each samosa costs ₹5. If you buy 1 samosa, you pay ₹5. If you buy 2 samosas, you pay ₹10. If you buy 3 samosas, you pay ₹15. So, ₹5, ₹10, ₹15 are all multiples of 5.

Worked Example

Step-by-Step

Let's find the first few multiples of 5.

Step 1: Multiply 5 by 1.
5 x 1 = 5

---
Step 2: Multiply 5 by 2.
5 x 2 = 10

---
Step 3: Multiply 5 by 3.
5 x 3 = 15

---
Step 4: Multiply 5 by 4.
5 x 4 = 20

---
Step 5: Multiply 5 by 5.
5 x 5 = 25

---
Answer: The first five multiples of 5 are 5, 10, 15, 20, and 25.

Why It Matters

Understanding multiples of 5 helps us count money quickly, tell time (minutes on a clock are in multiples of 5!), and even plan schedules efficiently. This skill is useful for shopkeepers, cashiers, and anyone managing budgets or planning events.

Common Mistakes

MISTAKE: Thinking that only numbers ending in 0 are multiples of 5. For example, some students might think 15 is not a multiple of 5 because it ends in 5, not 0. | CORRECTION: Multiples of 5 always end in either 0 or 5. Both are correct.

MISTAKE: Forgetting that 5 itself is a multiple of 5. Some students might start counting multiples from 10. | CORRECTION: The first multiple of any number is the number itself (when multiplied by 1). So, 5 x 1 = 5 is the first multiple.

MISTAKE: Confusing multiples with factors. For example, saying 2 is a multiple of 5. | CORRECTION: Multiples are numbers you get by multiplying. Factors are numbers that divide evenly into another number. 2 is a factor of 10, but not a multiple of 5.

Practice Questions

QUESTION: Is 35 a multiple of 5? | ANSWER: Yes, because 5 x 7 = 35.

QUESTION: List the next three multiples of 5 after 50. | ANSWER: 55, 60, 65.

QUESTION: A bus leaves the stand every 5 minutes. If the first bus leaves at 6:00 AM, at what time will the 5th bus leave? | ANSWER: The 5th bus will leave at 6:20 AM (6:00, 6:05, 6:10, 6:15, 6:20).

MCQ

Quick Quiz

Which of these numbers is NOT a multiple of 5?

100

The Correct Answer Is:

A, B, and D all end in 0 or 5, meaning they are multiples of 5. 82 ends in 2, so it cannot be divided by 5 without a remainder, making it not a multiple of 5.

Real World Connection

In the Real World

In India, many things are priced or counted in multiples of 5. For example, when you pay for groceries or an auto-rickshaw ride, the change you get often involves ₹5, ₹10, ₹20 notes or coins. Also, the time displayed on a clock's minute hand moves in steps of 5 (5 minutes, 10 minutes, 15 minutes, etc.).

Key Vocabulary

Key Terms

MULTIPLE: The result of multiplying a number by an integer | WHOLE NUMBER: Any positive number without fractions or decimals (0, 1, 2, 3...) | REMAINDER: The amount left over after division | PRODUCT: The answer when two or more numbers are multiplied together
