Final answer:
To estimate the sum of 5.82, 1.69, and 2.3, each number is first rounded off to the nearest whole number (6, 2, 2 respectively) and then added together to get the estimated sum of 10.
Explanation:
To estimate the sum of the decimal numbers 5.82, 1.69, and 2.3, we can follow the process of rounding off each number to the nearest whole number first before adding them.
Iterations are as follows: 5.82 can be rounded to 6, 1.69 can be rounded to 2, 2.3 remains 2.
After we have performed these rounding operations, we sum up the numbers obtained to get the estimated sum: 6+2+2 equals 10. Thus, the estimation of the sum of 5.82, 1.69, and 2.3 is 10.
