Question

Estimate the difference. Round each number to the nearest whole number, then subtract.
11 1/2 - 2 5/7


The difference is approximately .

Answer 1

First, let's round each number to the nearest whole number.

1. For \(11 \frac{1}{2}\):
- \(11 \frac{1}{2} = 11.5\)
- Rounding \(11.5\) gives us \(12\).

2. For \(2 \frac{5}{7}\):
- \(2 \frac{5}{7} = 2.7142857\) (approximately)
- Rounding \(2.7142857\) gives us \(3\).

Now, we subtract the rounded numbers:
\[
12 - 3 = 9
\]

Thus, the difference is approximately \(9\).
