Question

What is the greatest possible error for a measurement of 4 gallons?
gallons

Answer 1

To determine the greatest possible error for a measurement of 4 gallons, we first need to establish the context in which "greatest possible error" is defined. Often, this is described in terms of precision or uncertainty associated with the measurement.

If no specific precision or uncertainty is given, a common approach is to use a fraction of the measurement as the greatest possible error. A common assumption is to take 1% of the measured value as a potential error margin, though this is not a strict rule and might vary based on the context of the measurement equipment or method used.

1% of 4 gallons is calculated as follows:

\[
\text{Error} = 0.01 \times 4 = 0.04 \text{ gallons}
\]

Thus, the greatest possible error for a measurement of 4 gallons could be around ±0.04 gallons, assuming a common approximation of 1% error.

If you have specific instructions or contexts in which the measurement is taken (like the precision of the measuring instrument), please provide those details for a more accurate calculation.
