By rounding both numbers to the nearest hundred, we can estimate a sum of . Using the tool to model 325 + 169, we find the exact sum is .

Answer 1

To estimate the sum of 325 + 169 by rounding both numbers to the nearest hundred:

• 325 rounds to 300.
• 169 rounds to 200.

So, the estimated sum is: $$300+200=500.$$

Now, let's find the exact sum of 325 and 169: $$325+169=494.$$

Therefore, the estimated sum is 500 and the exact sum is 494.
