Question

Eric has a riddle: "I am thinking of a fraction that is equivalent to 25
and the numerator is 18 less than the denominator."

What is Eric's fraction?

Answer 1

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).
