Estimated the sum and differences

Question

179+277.1

Answer 1

To estimate the sum of 179 and 277.1, we can round the numbers to the nearest whole numbers:

• 179 rounds to 180
• 277.1 rounds to 277

Now, we can add the rounded numbers:

\( 180 + 277 = 457 \)

So, the estimated sum of 179 and 277.1 is 457.

For the difference, we can use the same rounded numbers:

• \( 180 - 277 = -97 \)

Therefore, the estimated difference is -97.

In summary:

• Estimated Sum: 457
• Estimated Difference: -97
