What is 12 ÷ 3?
Grade Level:
Class 2
Maths, Computing, AI
Definition
What is it?
12 ÷ 3 means we are taking a total of 12 items and dividing them equally into 3 groups. It tells us how many items will be in each group, or how many groups of 3 we can make from 12 items.
Simple Example
Quick Example
Imagine you have 12 ladoos. You want to share them equally among your 3 friends. How many ladoos will each friend get? This is exactly what 12 ÷ 3 helps us figure out.
Worked Example
Step-by-Step
Let's find out what 12 ÷ 3 is:
Step 1: Start with 12 items. Think of 12 small coins.
---
Step 2: We want to make groups of 3. Take 3 coins and put them aside as one group.
---
Step 3: You now have 12 - 3 = 9 coins left. Take another 3 coins to make a second group.
---
Step 4: You now have 9 - 3 = 6 coins left. Take another 3 coins to make a third group.
---
Step 5: You now have 6 - 3 = 3 coins left. Take these last 3 coins to make a fourth group.
---
Step 6: You have 3 - 3 = 0 coins left. You have made 4 groups of 3 coins each.
---
Answer: So, 12 ÷ 3 = 4.
Why It Matters
Understanding division is super important for many cool fields! In Computing, it helps computers share tasks or data equally. In AI, it's used to split up large problems for smart algorithms. Many jobs like data analysts or software engineers use division daily to manage resources efficiently.
Common Mistakes
MISTAKE: Confusing division with subtraction (e.g., thinking 12 ÷ 3 is 12 - 3 = 9) | CORRECTION: Remember division is about making equal groups or sharing, not just taking away once.
MISTAKE: Not knowing which number is being divided and which is the divisor (e.g., trying to do 3 ÷ 12 instead of 12 ÷ 3) | CORRECTION: The first number is always the total amount you are splitting, and the second number tells you the size of each group or how many groups to make.
MISTAKE: Only thinking about 'how many groups can I make' and forgetting 'how many in each group' (or vice-versa) | CORRECTION: Division answers both questions: how many groups of a certain size, or how many items in each group if you have a certain number of groups.
Practice Questions
Try It Yourself
QUESTION: You have 10 cricket balls. You want to put them into 2 equal bags. How many balls will be in each bag? | ANSWER: 5 balls
QUESTION: A mobile data pack gives you 15 GB of data. If you use 3 GB every day, for how many days will the data last? | ANSWER: 5 days
QUESTION: Your school has 20 students going on a trip. Each auto-rickshaw can take 4 students. How many auto-rickshaws are needed? | ANSWER: 5 auto-rickshaws
MCQ
Quick Quiz
What is the result of 18 ÷ 6?
12
3
6
18
The Correct Answer Is:
B
18 ÷ 6 means dividing 18 into 6 equal parts. If you count 6 groups of 3, you reach 18. So, 18 divided by 6 is 3. The other options are incorrect.
Real World Connection
In the Real World
When you're ordering food on an app like Swiggy or Zomato with friends and want to split the bill equally, you use division! Or when a shopkeeper needs to divide a large pack of biscuits into smaller, equal packs to sell, they also use division.
Key Vocabulary
Key Terms
DIVIDEND: The total number being divided (e.g., 12 in 12 ÷ 3) | DIVISOR: The number by which another number is divided (e.g., 3 in 12 ÷ 3) | QUOTIENT: The result obtained when one number is divided by another (e.g., 4 in 12 ÷ 3) | EQUAL SHARING: Distributing items so each part gets the same amount

What to Learn Next
Great job understanding basic division! Next, you can learn about 'Division with Remainders' where things don't always divide perfectly. This will help you solve even more real-life problems where items might be left over.
