Ratio
A ratio is a comparison of two quantities that are not equal but have the same relationship. This means that the ratio of two numbers is the same as the ratio of any other two numbers that are related to them.
For example, if you have two quantities, a and b, and a ratio of 2:3, this means that for every unit of a there are 3 units of b.
Equivalence Ratios:
Two ratios are equivalent if they are equal to each other. For example, if a ratio of 2:3 is equivalent to a ratio of 4:6, this means that 2/3 = 4/6.
Applications of Ratios:
Ratios have many applications in mathematics and other fields. For example, ratios are used to:
Calculate the speed of an object traveling at a constant velocity
Determine the amount of money needed to buy a certain amount of product
Analyze proportions of objects, such as the length of a person's body relative to their height
Examples:
If there are 6 apples and 8 oranges in a basket, the ratio of apples to oranges is 6:8.
If a car travels 30 miles in 1 hour, its speed is 30/1 = 30 miles per hour.
The ratio of the lengths of two similar triangles is equal to the ratio of the corresponding side lengths
