Which of the following represents the ratio of 2 to 3?

The ratio of 2 to 3 is represented as 2:3, which can also be expressed as a fraction. To translate the ratio into fractional form, you place the first number (2) over the second number (3). Therefore, the correct representation is 2/3.

Understanding ratios is essential because they denote a relationship between two numbers, highlighting how many times one value contains or is contained within the other. Thus, when you see the ratio 2:3, it indicates that for every 2 units of the first quantity, there are 3 units of the second quantity.

In contrast, the other options represent different numerical values and do not correctly describe the relationship presented in a 2 to 3 ratio. Therefore, option C accurately captures this mathematical relationship.
