Ratios are written in three different ways. The first is by a colon, written as "2:1." The second way a ratio is written is to utilize the word "to" instead of using a colon, as in the phrase "2 to 1." Ratios can also be written as a fraction with a slash, as in "2/1."

A rule of ratios is to divide or multiply numbers of the same value; the units must be the same so they can be comparable.
