Question
What is the estimate of the sum of 165, 123, 376 and 134 using front end estimation?
A. 600
B. 700
C. 800
D. 900
Solution
Front-end estimation makes use of the highest place value to estimate the sum. Here's how you can do it:
- For 165, the highest place value is 100. So, we take 100.
- For 123, the highest place value is 100. So, we take 100.
- For 376, the highest place value is 300. So, we take 300.
- For 134, the highest place value is 100. So, we take 100.
Now, add all these values together:
100 + 100 + 300 + 100 = 600
So, the estimate of the sum of 165, 123, 376 and 134 using front end estimation is 600. Therefore, the answer is A. 600.
