You start out with L inches of string.
You use %282%2F9%29L and then use another %281%2F4%29L of the string.
So then let's say you have X left.
%282%2F9%29L%2B%281%2F4%29L%2BX=L
X=L-%282%2F9%29L-%281%2F4%29L
Use a common denominator,
X=L-%282%2F9%29%284%2F4%29L-%281%2F4%29%289%2F9%29L
X=L-%288%2F36%29L-%289%2F36%29L
X=L%2836%2F36-17%2F36%29
X=%2819%2F36%29L
