A ratio is a comparison of two numbers that can be written in multiple ways such as:
Word: There are ___x for every ___ y
Fraction: y/x
Ordered pair: (x,y)
Ratio:x:y
Proportional is a type of relationship where, oh a graph, a line goes through the 0,0 point and when you divide y/x at any point, you will get the same answer.
