First of all, let's derive all the quantities. We know that Jermaine has [tex] t [/tex] tokes. So, if you have 4 more tokens, it means that you can start from this quantity, and add 4. In formula Karen has
[tex] K = t+4 [/tex]
tokens.
By the same logic, 5 fewer than a certain quantity means to subtract 5 from that quantity, so Raul has
[tex] R = t-5 [/tex]
tokens.
Now we're ready to write the ratio between the two numbers: simply put Karen's tokens [tex] K [/tex] at the numerator and Raul's tokens [tex] R [/tex] at the denominator and substitute [tex] K [/tex] and [tex] R [/tex] with the expressions we just found:
[tex] \frac{K}{R} = \frac{t+4}{t-5} [/tex]
Obviously, since we don't know the value of [tex] t [/tex], we can't say exactly how many tokens anyone has, or computing the ratio numerically, but only express it in terms of [tex] t [/tex].
