    10 1/2 -:- 2 1/4

    First, convert them into improper fractions:

    10 1/2 = 21/2

    2 1/4 = 9/4

    so now you have

    21/2 -;- 9/4

    To divide a fraction by a fraction, leave the first one alone, turn the second upside down and multiply:

    21/2 x 4/9

    Multiply the tops together and the bottoms together:

    = 84/18

    simplify (top and bottom are divisible by 6)

    = 14/3

    Convert back to mixed fraction by dividing 3 into 14:

    = 4 remainder 2

    = 4 2/3

    Convert both numbers into fractions.

    10 1/2 is 21/2 .. and .. 2 1/4 is 9/4

    Now, when dividing by a fraction you ''turn it over and multiply''

    So, 21/2 divided by 9/4 ... becomes 21/2 x 4/9

    21/2 x 4/9 = 84/18 .. which is 14/3 (divide 84 and 18 by their common factor, 6)

    and finally 14/3 becomes ... 4 2/3

    [ 21 / 2 ] [ 4 / 9 ] = 14 / 3

    21/2 / 9/4

    to divide, invert and multiply

    21/2 * 4/9

    now we can eliminate factors of (1):

    = (3/3) 7/2 * 4/3

    = 7/3 * 4/2

    = 7/3 * 2 *(2/2)

    = 14/3
