You can restate "one third" as "three ninths"; then subtracting three ninths from five ninths leaves two ninths:
5/9 - 3/9 = 2/9
Five eights is 40 which is much bigger than five ninths, which is less than 1.
Firstly, do 11 minus 4 = 7. So, now we have 7 and two ninths, minus five ninths. Much easier, 6 and 6 ninths.
