Final answer:
To represent the number of pasta packages which includes whole packages and one-third of a fourth package, we express the total as a mixed number combining the whole packages with the fractional package, for instance, 3 1/3 for three whole and one-third of another package.
Step-by-step explanation:
To represent the amount of pasta in packages, we note that there are a certain number of whole packages and then an additional one-third of a fourth package. To write this as a mixed number, we add the whole packages to the fractional package.
Let's say we have n whole packages. The mixed number representing the total packages would be n + 1/3. If, for example, there were 3 whole packages, then the mixed number would be 3 1/3. This denotes 3 whole packages plus one-third of another package.
