In a ratio of measurements for the same kinds of units, units get canceled. For example, in a ratio of 3 meters / 8 meters, you can cancel the "meters" in the numerator and the denominator. An important ratio is pi, which is the ratio of the circumference of a circle to its diameter. If you measure the circumference in feet, and the diameter in feet, then divide circumference/diameter, then the result is the dimensionless quantity 3.14159265.... If you go back and measure both in meters, you get the same answer.
In a ratio of two measurements, the units cancel, so it makes no difference whether you write the units, or not.

What is the ratio of 31 to 13?
The ratio of 31 to 13 can be expressed as 31:13. To simplify, you can divide both numbers by their greatest common divisor, which is 1 in this case, so the ratio remains 31:13. This indicates that for every 31 units of one quantity, there are 13 units of another.
