Final answer:
Cara needs 6.25 meters of ribbon for her party.
Step-by-step explanation:
To find the answer, we need to consider that Cara needs 25 cm of ribbon for each of the 25 balloons. So, the total length of ribbon needed is 25 cm x 25 balloons = 625 cm.
However, we need to convert the length from centimeters to meters.
Since 1 meter is equal to 100 centimeters, we can divide 625 cm by 100 to get the length in meters:
625 cm ÷ 100 = 6.25 meters.
Therefore, Cara needs 6.25 meters of ribbon for her party.
