Final answer:
Tomás can make 28 packages of 1/4-pound fruit snacks with the given amount of peaches, grapes, and raspberries, by dividing the total weight of 7 pounds by 1/4 pound. Hence Tomás can put together 28 packages of 1/4 pound each.
Step-by-step explanation:
To determine how many 1/4-pound fruit snack packages Tomás can put together with 1 1/2 pounds of peaches, 3 1/2 pounds of grapes, and 2 pounds of raspberries, we first need to calculate the total weight of all fruits combined. We add 1 1/2 pounds + 3 1/2 pounds + 2 pounds to get a total of 7 pounds of fruit.
Next, since each package is 1/4 of a pound, we divide the total weight of the fruits by 1/4 pound to determine the number of packages Tomás can make. Dividing 7 pounds by 1/4 pound gives us 28 packages, because 7 divided by 1/4 is the same as 7 multiplied by 4.
