Final answer:

To determine the amount of gravel in a 1-pound mixture, calculate the proportion of gravel in the original 56-pound mixture, which is 25%, and then apply this proportion to 1 pound, resulting in 0.25 pounds or 1/4 pound of gravel in a 1-pound mixture.

Step-by-step explanation:

To find out how much gravel is in a 1-pound mixture based on the information that there are 14 pounds of gravel in a 56-pound mixture, we need to use the concept of ratios or unitary method. We divide the amount of gravel by the total weight of the mixture to get the proportion of gravel to the whole mixture.

The proportion of gravel in the mixture is 14 pounds of gravel/56 pounds of mixture, which simplifies to 1/4 or 0.25. This means that 25% of the mixture is made up of gravel. Therefore, in a 1-pound mixture, the amount of gravel would be 0.25 pounds or 1/4 pound.
