Answer :
Answer:
12000
Step-by-step explanation:
1. front end estimation:
Identify the front-end digits (the digits in the highest place value):
2346 --> 2000
2355 --> 2000
6510 -->6000
910 --> 0 (since it has fewer digits, we can consider it as 0 for the thousands place)
Add the front-end values:
2000+2000+6000=10000
2. Adjustment:
Now, let’s look at the next digit (the hundreds place) to make an adjustment:
2346 -> 300
2355 -> 300
6510 -> 500
910 -> 900
Add the hundreds place values together: 300+300+500+900=2000
Add this adjustment to the initial front-end estimate: 10000+2000=1200
