To find Eric's fraction, we need to determine a fraction that is equivalent to 25 and has a numerator 18 less than the denominator.
Let's assume the denominator of the fraction is x.
So, the numerator of the fraction is x - 18.
Now, we can set up the equation:
(x - 18) / x = 25
To solve for x, we can cross-multiply:
25x = x - 18
Simplifying the equation:
25x - x = -18
24x = -18
x = -18 / 24
x = -3/4
Therefore, Eric's fraction is (-3/4).
