Answer:
1219.5 more centimeters of fabric
Explanation:
First, we need to convert 12.5 meters to centimeters, since the given amount of fabric is in centimeters.
12.5 meters = 12.5 x 100 centimeters/meter = 1250 centimeters
Now we can find the difference between what Ray needs and what he has:
1250 centimeters - 30.5 centimeters = 1219.5 centimeters
Therefore, Ray needs 1219.5 more centimeters of fabric.
