Definition
What is it?
12 ÷ 2 means dividing the number 12 into 2 equal parts. It tells us how many items each part will have if we share 12 things equally between 2 groups.
Simple Example
Quick Example
Imagine you have 12 ladoos. You want to share them equally with your friend. How many ladoos will each of you get? You are dividing 12 ladoos into 2 equal shares.
Worked Example
Step-by-Step
Let's find out what is 12 ÷ 2.
Step 1: We have 12 items to share.
---
Step 2: We want to share them equally among 2 groups.
---
Step 3: You can think of it as asking: 'What number, when multiplied by 2, gives us 12?'
---
Step 4: Let's count by 2s: 2 x 1 = 2, 2 x 2 = 4, 2 x 3 = 6, 2 x 4 = 8, 2 x 5 = 10, 2 x 6 = 12.
---
Step 5: We found that 2 multiplied by 6 gives 12.
---
Step 6: So, 12 divided by 2 is 6.
Answer: 12 ÷ 2 = 6
Why It Matters
Understanding division helps you in many fields like Computing, where you might divide tasks among processors, or in AI, where data is split for training models. Even game developers use division to balance game resources or player scores. These skills are important for careers in technology and science.
Common Mistakes
MISTAKE: Students confuse division with subtraction, thinking 12 ÷ 2 is 12 - 2 = 10. | CORRECTION: Division is about splitting into equal groups, not just taking away.
MISTAKE: Students guess the answer without checking with multiplication. | CORRECTION: Always check your division answer by multiplying it by the divisor. For 12 ÷ 2 = 6, check 6 x 2 = 12.
MISTAKE: Writing the answer as the divisor (2) instead of the quotient (6). | CORRECTION: The answer to a division problem is how many are in each group, not how many groups you are dividing by.
