A Ratio is a relationship between two quantities based on division between the two.

**Context**- It can expressed with a Ratio Statement.
- It is a dimensionless number, A and B have the same units of measurement.
- ...

**Example(s)**- If A = 12 and B = 8, the ratio of A to B is 12/8=
**3/2**or**3:2** - a Ratio Measure.
- …

- If A = 12 and B = 8, the ratio of A to B is 12/8=
**Counter-Example(s)**- Rate.

**See:**Fraction, Ratio Statement, Ratio Value, Numerator, Denominator.

- The ratio of two numbers r and s is written r/s, where r is the numerator and s is the denominator. The ratio of r to s is equivalent to the quotient r/s. Betting odds written as r:s correspond to s/(r+s). A number which can be expressed as a ratio of integers is called a rational number.

**ratio**is a relationship between two numbers indicating how many times the first number contains the second. For example, if a bowl of fruit contains eight oranges and six lemons, then the ratio of oranges to lemons is eight to six (that is, 8:6, which is equivalent to the ratio 4:3). Thus, a ratio can be a fraction as opposed to a whole number. Also, in this example the ratio of lemons to oranges is 6:8 (or 3:4), and the ratio of oranges to the total amount of fruit is 8:14 (or 4:7).The numbers compared in a ratio can be any quantities of a comparable kind, such as objects, persons, lengths, or spoonfuls. A ratio is written "

*a*to*b*" or*a*:*b*, or sometimes expressed arithmetically as a quotient of the two. When the two quantities have the same units, as is often the case, their ratio is a dimensionless number. A rate is a quotient of variables having different units. But in many applications, the word*ratio*is often used instead for this more general notion as well.
