For example, if you earn $10 in 3 hours, and you want to know how much you earn per hour, this is equivalent to solving the proportion:
10/3 = x/1
rate = distance / time (r= d/t)
It represents a direct proportion and whose graph is a straight line through the origin.
The rate, or rate of change is like an average all except it has to do with the slope of a line instead of a group of numbers. Finding the rate of change is like finding an average except you use the points on the graph instead of numbers in a group.
The slope of a line is the same thing as the rate of change between two variables in a linear relationship.
an example of a ratio is the difference between two numbers or sets of numbers such as 600 and 200... the ratio is 400...
A proportion is an equation in which 2 fractions are set equal. A rate is the ratio of change of two things. Speed is a rate, the ratio of distance to time.

When solving rate and ratio problems, it's crucial to clearly identify the quantities involved and their relationships. Always ensure that units are consistent; for example, if you're dealing with speeds, make sure both distances and times are in compatible units. Set up a proportion or equation based on the information given, and simplify wherever possible. Lastly, double-check your calculations to ensure accuracy in your final answer.
