Final answer:

Estimation offers quick approximations but less accuracy, while measurement is more accurate and minimizes uncertainty but requires more time and specific tools.

Step-by-step explanation:

When comparing estimation and measurement using a measuring tool, each method has its advantages and disadvantages. Estimation is a method where one makes an educated guess about a quantity, whereas measurement is when one uses tools to determine an exact value.

The ease of estimation versus measurement depends on the situation. For example, estimation can be faster and more convenient when an approximate value is sufficient. Estimating the width of a desk using the width of one's hand is an example of this. However, estimation is less accurate and can lead to greater uncertainty in results, which is undesirable in situations requiring precise data.

On the other hand, measurement is generally more accurate, especially when using high-precision tools like a ruler with millimeter markings. The use of such tools reduces the uncertainty of the results, which is crucial for tasks requiring high precision. A limitation of measurement is that it can be more time-consuming and requires access to the appropriate measuring tool. Measurement tools also vary in their precision, which can be seen when comparing a ruler with centimeter markings to one with millimeter markings, where the latter provides more accurate and precise measurements.

To summarize, estimation offers quick approximations with less precision, while measurement provides exact values and minimizes uncertainty but requires more time and access to the proper tools.
