Question
Estimate the difference by first rounding each number to the nearest hundred.
6879 - 2869 ≈
Solution
Sure, let's estimate the difference by rounding each number to the nearest hundred.
First, round 6879 to the nearest hundred. The tens digit is 7, which is greater than 5, so we round up. 6879 rounds up to 6900.
Next, round 2869 to the nearest hundred. The tens digit is 6, which is greater than 5, so we round up. 2869 rounds up to 2900.
Now, subtract the rounded numbers:
6900 - 2900 = 4000
So, 6879 - 2869 is approximately 4000 when rounded to the nearest hundred.
