Using proportions, it is found that there are 22 rungs in the whole ladder.
What is a proportion?
A proportion is a fraction of a total amount, and the measures are related using a rule of three. Due to this, relations between variables, either direct or inverse proportional, can be built to find the desired measures in the problem.
She climbed up five rungs, moved down two rungs, and then climbed up six rungs, then she climbed up the remaining two rungs, hence half the number of rungs is given by:
H = 5 - 2 + 6 + 2 = 11.
The total amount is given as follows:
0.5x = 11.
x = 11/0.5
x = 22.
There are 22 rungs in the whole ladder.
