Question

which pair of numbers shows the second number is an estimation of the first? • 0.00345; 0.003 • 345; 400 • 275; 200 • 0.00345; 0.004

Answer 1

To determine which pair of numbers shows the second number as an estimation of the first, we can compare the values and determine if the second number is a close approximation of the first number.

Let's evaluate each pair of numbers:

1. 0.00345; 0.003: The second number (0.003) is a close approximation of the first number (0.00345). Therefore, this pair shows the second number as an estimation of the first.

2. 345; 400: The second number (400) is not a close approximation of the first number (345). Therefore, this pair does not show the second number as an estimation of the first.

3. 275; 200: The second number (200) is not a close approximation of the first number (275). Therefore, this pair does not show the second number as an estimation of the first.

4. 0.00345; 0.004: The second number (0.004) is not a close approximation of the first number (0.00345). Therefore, this pair does not show the second number as an estimation of the first.

Based on the evaluation, the pair "0.00345; 0.003" shows the second number as an estimation of the first.
