Y:4,2=3,4:51

It seems like you're providing a ratio or a set of proportions, but it's not entirely clear what you're asking.

If you're looking to simplify or solve for a variable in the context of a ratio, could you please clarify the question or the relationship you are trying to establish? For example, are you looking to find the value of \( y \) or something else? Providing a bit more context would be helpful!
