Estimate the difference. Round each number to the nearest whole number, then subtract.

Question

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 \(9\).
