Best Answer

A propotion is a math method. For example 3 over 100 = x over 50, you crossmultipy both 3 times 50 and 100 times x, then you'll get 150 = 100x, then you have to get x by itself so you divide 100 from both sides and that leaves you with x = 1.5.The proportion in this problem is 3 over 100 = x over 50
