From the information given, what is the necessary computation for the trail mix bags to maintain proportions?

To determine the necessary computation for the trail mix bags to maintain proportions, one must analyze the ratio of components in the mix. In this scenario, if the ratio of nuts to the total mix is significant, you are likely trying to find a fraction that accurately represents this ratio while ensuring the ingredients blend well together.

When considering the fractional options given, 2/5 of the mixture signifies that for every five parts of the trail mix, two parts should be nuts. This ratio is an effective way to maintain the proportions if the recipe or mix's intended balance calls for two parts nuts out of five total parts.

By establishing that two-fifths of the mixture should consist of a particular ingredient (in this case, nuts), it ensures that the other components also retain their proper ratios, allowing for a harmonious combination of flavors and textures in the trail mix. This fraction aligns with maintaining the intended recipe proportions, making it the correct choice.
