There are 54 students and 18 computers in a classroom. Which ratio accurately compares the number of students to the number of computers?

Answer 1

#3:1# or #3/1# or #3# or "#3# to #1#"

Since there are 54 students and 18 computers, and we need a ratio of students to computers, we don't need to rearrange anything. We can set up the following ratio of 54:18 or #54/18#. This ratio, however, is not yet reduced to its simplest form. To reduce we can divide both numbers by 18, which results in the ratio 3:1 or #3/1#. Depending on personal preference, any of the above ways of writing the ratio can work.

The ratio that accurately compares the number of students to the number of computers is:

54 students : 18 computers.
