Final answer:
Reese will need 5/8 yards of blue ribbon for every yard of gold ribbon she uses.
Step-by-step explanation:
To find out how much blue ribbon Reese will need for every yard of gold ribbon she uses, we can set up a proportion using the given information.
Reese needs 1 4 yard of blue ribbon for every 5 8 yard of gold ribbon. Let's represent this as:
1 4 / 5 8 = x / 1
Now, we can cross multiply:
8 * x = 1 * 5
x = 5/8
Therefore, Reese will need 5/8 yards of blue ribbon for every yard of gold ribbon she uses.
