Calculate Percentage in Easy Method Question: 10% of 15000 1. First, cancel the last two zeros. 2. Then, divide 150 by 10. You will get the answer.
The correct answer and explanation is:
โ Correct Answer:
10% of 15,000 = 1,500
๐ Easy Method Explanation (Step-by-Step)
Step 1: Cancel the last two zeros from 15,000
We start with:
10% of 15,000
Removing the last two zeros from 15,000, we are left with:
150
Step 2: Divide 150 by 10
Now take:
150 รท 10 = 15
But remember, we canceled two zeros earlier. That means we temporarily reduced the number to make calculations easier. Now we need to restore those two zeros.
So, take 15 and add two zeros back, we get:
1,500
This is the correct answer.
๐ง Why This Works (Concept Behind the Method)
A percentage means “per hundred.” So:
10% means 10 out of every 100, or 10 รท 100 = 0.10
To find 10% of any number, you multiply the number by 0.10:
15,000 ร 0.10 = 1,500
This is the standard method.
But the trick method we used is based on mental math shortcuts. Canceling two zeros from both the percentage (100) and the number (15,000) simplifies the operation.
For example:
- 100% of 15,000 = 15,000
- 10% = 1/10 of that = 1,500
- We simplify 15,000 by dropping two zeros โ 150
- Then divide 150 by 10 โ 15
- Restore the zeros โ 1,500
๐ก Bonus Tip:
This trick works well for finding 10%, 20%, 50%, and even 5% of big round numbers (like 10,000, 25,000, etc.), because percentages are all fractions of 100 and zeros can be temporarily canceled to simplify.
โ Final Answer:
10% of 15,000 = 1,500
