    If you make everything have the same denominator, then Joel would have walked 8/20 of a mile to the store, 6/20 of a mile to the library, and 1/20 of a mile to the post office. When you add them up, Joel walked 15/20 of a mile or 3/4

    You need equivalent fractions with the same denominator.

    2/5 = 8/20
    3/10 = 6/20

    1/20 + 8/20 + 6/20 = ?

    3/10

    15/20
