What fraction is equivalent to the whole number 6?

Well, any fraction which result gives you 6 is a fraction that would fulfill the requirement, I'll give you a few examples so you can grasp the idea:

6 = 6/1 = 12/2 = 18/3 = 24/4 = 30/5 = 36/6 = 42/7 = 48/8 = 54/9 = 60/10

Ad libitum [116K]

$5^2 + 12^2 = 13^2$

is the second or third Pythagorean triple on the list, which gives us the answer directly.

But if we didn't know that, let x be the short leg:

$x^2 + (x+7)^2 = 13^2$

$2x^2 + 14 x + 49 - 169 = 0$

$x^2 + 7x - 60 = 0$

$(x+12)(x-5)=0$

Rejecting the negative root, x=5, other side 12, the Pythagorean triple we found.
