If A = 8 and B = 2, what is A's ratio to B?

To find the ratio of A to B, you take the values given for A and B and express the relationship between them as a fraction. In this question, A is 8 and B is 2. The ratio of A to B can be calculated by dividing A by B, which results in:

[

\text{Ratio} = \frac{A}{B} = \frac{8}{2} = 4

]

This means that A is 4 times larger than B. Ratios are typically expressed in a way that highlights the comparison between the two numbers. In this simplest form, the ratio can also be written as 4:1, indicating that for every 1 unit of B, there are 4 units of A.

The choice that conveys this relationship correctly is 4:1, which explicitly reflects the values calculated. In the context of the choices provided, this is the most accurate way to express the ratio.
