Answer:
10 ornaments
Step-by-step explanation:
You would have to divide 5 feet by how much it takes to make an ornament, 1/2 foot.
[tex]5 / \frac{1}{2}[/tex] = [tex]\frac{5}{1} / \frac{1}{2}[/tex]
To divide by a fractions, you will need to multiply the first number by the number you're dividing by's reciprocal:
[tex]\frac{5}{1} * \frac{2}{1}[/tex] = [tex]\frac{10}{1}[/tex]
= [tex]10[/tex]
