To find the fraction, let's assign variables to the numerator and denominator. Let's say the numerator is represented by "x" and the denominator is represented by "y".
According to the problem, the numerator is 5 less than the denominator, so we can form an equation: x = y - 5.
Additionally, if we add 6 to the numerator and 4 to the denominator, the resulting fraction is double. We can now write another equation: (x + 6) / (y + 4) = 2.
Now that we have two equations, we can solve them simultaneously to find the values of x and y.
From the first equation, x = y - 5, we can substitute this relationship into the second equation:
((y - 5) + 6) / (y + 4) = 2.
Simplifying this equation, we get: (y + 1) / (y + 4) = 2.
We can now cross-multiply to solve for y:
y + 1 = 2(y + 4),
y + 1 = 2y + 8,
y - 2y = 8 - 1,
-y = 7.
Multiplying both sides of the equation by -1 to solve for y, we get y = -7.
Now that we have the value for y, we can substitute it back into the first equation to find x:
x = y - 5 = -7 - 5 = -12.
Therefore, the fraction is -12/-7. However, we can simplify it by dividing both numerator and denominator by their greatest common divisor, which is 1. So the final simplified fraction is:
12/7.
Hence, the fraction is 12/7.
