Solve the Division Problem: Calculate 10:10

Q: Why isn't the answer 0 since 10 - 10 = 0?

Great question! Division is not the same as subtraction. When we write $ 10 \div 10 $, we're asking 'how many groups of 10 can we make from 10?' The answer is exactly one group.

Q: What does the identity property mean?

The identity property of division says that any number divided by itself always equals 1. Think of it like this: if you have 10 cookies and divide them equally among 10 people, each person gets 1 cookie!

Q: Does this work with any number?

Yes! Any non-zero number divided by itself equals 1. So $ 5 \div 5 = 1 $, $ 100 \div 100 = 1 $, and even $ 0.5 \div 0.5 = 1 $!

Q: What about 0 ÷ 0?

$ 0 \div 0 $ is undefined in mathematics. The identity property only works with non-zero numbers. Zero has special division rules that are different!

Q: How can I remember this rule?

Think of sharing: if you have 10 items to share equally among 10 people, each person gets exactly 1 item. The number of items per person is always 1 when the total equals the number of people!

Understand the problem

$10:10=$

Step-by-step solution

To solve this problem, we'll apply the identity property of division, which states that any non-zero number divided by itself equals 1.

Step 1: Identify the numbers: $10 \div 10$ .
Step 2: Apply the identity property: $(10 \div 10 = 1)$ .

Applying this property, we find that dividing 10 by 10 results in 1:

$10 \div 10 = 1$

Therefore, the solution to the problem is $1$ , which corresponds to choice 3.

Identity Rule: Any non-zero number divided by itself equals 1
Technique: Recognize $10 \div 10$ as the identity property
Check: Verify that $1 \times 10 = 10$ ✓

Common Mistakes

Avoid these frequent errors

Thinking division means subtraction
Don't subtract and think 10 - 10 = 0! This confuses subtraction with division and gives the wrong operation. Always remember division asks 'how many groups' not 'what's left over'.
