Angela is building a pool that is 25 meters long. She has selected tile to put around the edge of the pool. Each tile is 8 inches long. How many tiles will she need for one 25-meter side of the pool?   1 meter = 3.283 feet 1 foot = 12 inches In order to do conversion on these types of problems. 
1. You first have to determine the relationship and the current unit and the target unit which it will be converted into. 
2.In this case feet to meters and seconds to minutes 
3.Determine the conversion rate which is above.
4.You first calculate: 8 in x 1 foot/ 12 inches = 0.7 foot
5.Next, is the time which is 0.7 foot x 1 m / 3.283 feet = 0.20 m
6.25 m/0.20m = 125 tiles
