Let's assume the numerator is x. Then the denominator is x + 2.
Since the fraction is equivalent to 39/1, we can write the following equation:
x / (x + 2) = 39 / 1
To solve for x, we can cross multiply:
x * 1 = 39 * (x + 2)
x = 39x + 78
Subtract 39x from both sides:
x - 39x = 78
-38x = 78
Divide both sides by -38:
x = -2.05
Since the numerator cannot be negative, we can conclude that the numerator is 2.
Therefore, the fraction Roberto is thinking of is:
numerator: 2
denominator: 2 + 2 = 4
So, Roberto is thinking of the fraction 2/4.
