**What is a Ratio?**

A ratio is a comparison of two numbers or two

amount that can be expressed in the following

three ways:

as a Fraction

with a colon (:)

using the word “to”

Example:

Suppose you are told that there are three teachers for

every 12 students at your son School. The three ways this

ratio of teachers to students can be written are:

**Ratio of teachers to students**

**12/312:312 to 3**

Notice that in each case, the number of teachers is written first (or

in the numerator of the fraction). This is because the problem

stated that we were to express the ratio of teachers to students.

Typically the first thing mentioned in a ratio problem is what is

listed first.

If the problem had asked us to express the number of students to

teachers , each of our ratios would be written in the opposite

order:

**Ratio of students to teachers12/312:312 to 3**

Question

A owner at a local restaurant notes that during the day his

customers ordered 3 breakfast meal for every 1 diner meal .

Express the ratio of breakfast meal to dinner meals.
