Final answer:
The ratio of 'eight plus a number' to 'another number' should be written as (8 + x) / y, where x and y are the variables. None of the given options correctly represent this ratio.
Step-by-step explanation:
The ratio of eight plus a number to another number in expression form can be represented algebraically. When we write ratios, they can be expressed similarly to fractions, thus making the notation for the given statement (8 + x) / y where x and y are the variables representing numbers.
It is important to include brackets around 8 + x to ensure that the addition occurs before the division, as per the order of operations. Considering the provided options, none of them correctly expresses this ratio, so the correct expression does not appear to be listed.
