Question
Use the clustering estimation technique to find the approximate total in the following question.What is the estimated sum of 503, 472, 486, 499, 539, and 522? A. 2,800 B. 3,000 C. 3,100 D. 4,000
Solution
The clustering estimation technique involves rounding numbers to the nearest hundred, ten, or other convenient number to make calculations easier.
Here's how you can use it to estimate the sum of 503, 472, 486, 499, 539, and 522:
-
Round each number to the nearest hundred:
- 503 rounds to 500
- 472 rounds to 500
- 486 rounds to 500
- 499 rounds to 500
- 539 rounds to 500
- 522 rounds to 500
-
Add the rounded numbers together:
- 500 + 500 + 500 + 500 + 500 + 500 = 3000
So, the estimated sum of 503, 472, 486, 499, 539, and 522 using the clustering estimation technique is 3000. Therefore, the answer is B. 3,000.
