the product is approximately

Answer 1

To estimate the product of 22 and 2.3 by rounding each number to its greatest place value:

1. Round 22 to its greatest place value: 22 rounds to 20.
2. Round 2.3 to its greatest place value: 2.3 rounds to 2.

Now, multiply the rounded numbers:

\[ 20 \times 2 = 40 \]

Therefore, the estimated product of 22 x 2.3 is approximately 40.
