Marsha has three rugs. The first rug is 2 meters 87 centimeters long The second rug has a length 98 centimeters less than the first. The third rug is 111 centimeters longer than the second rug. what is the difference in centimeters between the length of the first rug and the third rug?

Well, a meter is = to 100cm right? So the first rug would be 287cm. Then, the second rug is 98cm less than the first rug so you subtract the first rug with the second rug. After you found out what the second rug's length is, then you would add the second rug to 111 which is the third rug. Finally, you add the first rug to the third rug.
