Ratios are used within Mathematics. A ratio is simply the relationship between two numbers, it indicates how many times the first number contains the second number. An example of a ratio is that you have 2 flashlights and 5 batteries. To compare the ratio between the flashlights and the batteries we divide the set of flashlights with the set of batteries. The ratio is 2 to 5 or 2:5 or 2/5. Whereas a non-example of ratios is simply not putting the correct numbers in the correct arrangement. An example of this would be; Mario had 9 marbles and Stacy had 14 marbles what is the ratio to the number of marbles of Mario to Stacy.
example of ratio: 9:14 or 9/14 or 9 to 14
non-examples of a ratio: 2:19 or 2/19 or 2 to 19
