Final answer:
Tia can complete 8 projects with her 28 yards of fabric by dividing the total yards by the yards required for one project, which is 3.5 yards.
Step-by-step explanation:
Tia has 28 yards of fabric and each project requires 3 and one half yards. To calculate how many projects she can complete, we divide the total yards of fabric by the amount needed for one project. In mathematical terms, this is expressed as 28 yards ÷ 3.5 yards per project.
When we carry out this division, we find that 28 ÷ 3.5 equals 8. Therefore, Tia can complete 8 projects with the 28 yards of fabric she has.
It is important to know that 3 and one half yards is equal to 3.5 yards, which simplifies our calculations. As a result, Tia can efficiently allocate her fabric to complete a whole number of projects without any waste.
