Final answer:
Front-end estimation for adding 495, 650, and 875 involves adding the front-end digits (4, 6, and 8) from the hundreds place, resulting in an estimated sum of 1800, which is an approximation of the total sum.
Step-by-step explanation:
To use front-end estimation to add 495, 650, and 875, you first look at the front-end digits of each number, which are the digits in the highest place value. Here, those digits are 4, 6, and 8 respectively (all from the hundreds place). You would add these three digits first.
To perform the front-end estimation:
- Add the hundreds digits: 4 (from 495) + 6 (from 650) + 8 (from 875) = 18.
- Since there are no thousands digits, the 18 becomes 1800 when considering the hundreds place.
- The front-end estimation sum is 1800, which is the approximate sum of the three numbers.
It's important to note that front-end estimation provides an approximation, not the exact sum. When using this method, you may add or subtract a little from the result to account for the remaining digits.
