To find out how many yards of ribbon Olivia needs for 18 balloons, we first need to figure out how much ribbon she uses for one balloon and then multiply that by the number of balloons.
Given that Olivia ties 2.5 feet of ribbon onto one balloon, we need to convert this to yards because the final answer should be in yards. Since there are 3 feet in a yard, we can use that conversion factor.
To convert 2.5 feet to yards, we divide it by 3:
2.5 feet รท 3 = 0.8333 yards
So, Olivia uses approximately 0.8333 yards of ribbon for one balloon.
Now, to find out how much ribbon she needs for 18 balloons, we can simply multiply the amount of ribbon used for one balloon by the number of balloons:
0.8333 yards/balloon * 18 balloons = 15 yards
Therefore, Olivia needs approximately 15 yards of ribbon for 18 balloons.
