An artificial lake is in the shape of a rectangle and has an area of 9/20. The width of the lake is 1/5 the length of the lake. Waht are the dimensions of the lake?
the answer is 10/20 because your supposed to find the common denominator for 20 and 5 and that is 20. Then you add 9 plus 1 and that's 10 so that will make 10/20.
