+%28sqrt%2820%29%29%2F%28sqrt%2815%29%29+
First, rationalize the denominator by multiplying both the numerator and the denominator by sqrt15
+%28sqrt%2820%29sqrt%2815%29%29%2F%28sqrt%2815%29sqrt%2815%29%29+
Multiply in the denominator
+%28sqrt%2820%29sqrt%2815%29%29%2F15+
root out the 20 and 15
+%28sqrt%282%2A2%2A5%2A5%2A3%29%29%2F15+
Pull out the pairs. Remember that only one of the pair is written on the outside
+%282%2A5sqrt%283%29%29%2F%2815%29+
Multiply
+%2810sqrt%283%29%29%2F%2815%29+
Reduce
+%282sqrt%283%29%29%2F%285%29+
