Question

Estimate and compare with the actual sum:

$760+683$

Answer 1

Step-1: Find the estimated values of both numbers to their nearest hundreds-

The estimated value of $760$ to its nearest hundreds is $800$ as the digit at tens place is $6$ which is greater than $5$.

The estimated value of $683$ to its nearest hundreds is $700$ as the digit at tens place is $8$ which is greater than $5$.

Step-2: Find the estimated sum-

Estimated sum:

$800+700=1500$

Step-3: Find the actual sum-

Actual sum:

$760+683=1443$

Step-4: Compare both the values by finding difference

Difference

$\Rightarrow 1500-1443=57$

Hence, the required difference is calculated.
