Now that you've created your hypothesis it's time to prove them first look at the sum of two rational numbers let's say they are two rational numbers X and y. Because they are rational they can be written as a ratio of integers Let X= a/b and Y=c/d where a, b,c and d are integers and b and d do not equal 0. The process for finding the sum X+Y in terms of a, b,c and d is shown. Based on the sun and using the closure property of integers what conclusion can you make about the sum of two rational numbers explain your answer
