You divide 9/5, and the first number you get will be the whole number, the bottom number will be the numerator of the fraction (the top) and the number you are dividing (is on the outside of the box) will be the denominator (bottom number).
Or you can see how many times 5 goes into 9, and whatever the number goes into it (doesn't have to go straight in) will be the whole number. Then, you subtract 9 and the number that is your whole number times 5, and whatever you get will be your numerator. The denominator will be the bottom number of 9/5.
There you go! That is how you find 9/5 as a mixed number!
