To find the total length of ribbon that Turner needs, we can use the equation:
Total length of ribbon = Length of one piece of ribbon × Number of pieces of ribbon
In this case, the length of one piece of ribbon is given as 3/4 foot. The number of pieces of ribbon needed is 9.
Substituting these values into the equation, we have:
Total length of ribbon = (3/4 foot) × 9
To multiply fractions, we multiply the numerators together and then multiply the denominators together. Hence, the equation becomes:
Total length of ribbon = (3 × 9) / (4 × 1) foot
Simplifying further:
Total length of ribbon = 27/4 foot
So, Turner needs a total length of 27/4 foot of ribbon for his costume.
