    If she ran 1 1/8 miles(equals 9/8) and then 2 miles(equlas 16/8), add them together and subtract them from the distance she need to run.

    that is right so far. now, in order to add fractions, the denominators, the number at the bottom, must be equal. Did you know that?

    good. so you need to find a number that, if you divide it by 8, you get 5. what number is this?

    think about it like this. you are addding 25/8 +5, but you can't do it yet because the denominators are not the same. so what can you do to 5 to let it have a denominator of 8?

    you can divide it by 40

    right!:) good job. ok. i made a mistake earlier when I said you are adding 25/8 +5. really, you are doing this: 5-25/8. Can you take it from here?
