Answer:
0.25 ounces
Explanation:
To find out how many ounces of sequins John will use on each project, we can divide the total amount of sequins (3 ounces) by the number of projects (12).
3 ounces ÷ 12 projects = 0.25 ounces per project
So John will use 0.25 ounces of sequins on each project.
We can write the division problem as a fraction:
3 ÷ 12 = 0.25
To solve using an area model, we can draw a rectangle with one side labeled 3 and another side labeled 12, representing the number of ounces of sequins and the number of projects, respectively. We can then divide the rectangle into 12 equal parts to represent each project. The area of each part will represent the number of sequins used on each project.
Using this model, we can see that each part has an area of 0.25 square units, which represents 0.25 ounces of sequins. Therefore, the answer is still 0.25 ounces per project.
