The ladder, wall and floor together form a right triangle with the length of the ladder being the hypotenuse, the distance of the foot of the ladder from the wall being one of the shorter sides and the distance between the top of the ladder and the floor being the other side
We can use the Pythagorean theorem to solve for the hypotenuse given the two sides
The general formula is:
where c is the hypotenuse and a and b the other two sides
you have to subtract the numerator of the improper fraction from the denominator and the number you have left is the fraction like for 4/3 4-3=1 so the fraction is 1/3 the amount that is NOT a fraction counts as the whole depending on how many times it can go into the denominator.
You have to calculate the rise over run. See how many times it rises from the bottom. Then see how many times it takes horizontally to get to the next corner. Not sure if this helped but I tried sorry lol (but dw the answer is correct)
