    okay so now, 26/15 divided 39/20 you know that when dividing by fractions, you multiply by the reciprocal of the second fraction so 26/15 divided 29/20 is equivalent to 26/15 x 20/39

    first you have to turn both fractions into improper fractions. 1 11/15= 26/15, 1 19/20 =39/20. To divide them, it is the same as taking the first fraction and multiplying that by the reciprocal of the second one, so it is 26/15 x 20/39 and you multiply that straight across, then simplify.
