  1. (3+3/5) / (2+ 1/2)=

    =(3+6/10) / (2+5/10)

    =(3.6)/(2.5)=36/25


  2. 18/5 / 5/2

    same as

    18/5 X 2/5

    same as

    36/25 = 1 11/25

  3. 3 = 15/5

    15/5 + 3/5 = 18/5

    2 = 4/2

    4/2 + 1/2 = 5/2

    (18/5)*(2/5) = 36/25 = 1 and 11/25

  4. 3 3/5 = (3*5 + 3) / 5 = 18/5

    2 1/2 = (2*2 + 1) / 2 = 5/2

    18/5 / 5/2 = 18/5 * 2/5 = (18 * 2) / (5 * 5) = 36/25 = 1 11/25

  5. 3 3/5 = (3*5 + 3) /  5 = 18/5.

    2 1/2 = (2*2 + 1 )/2 = 5/2

    18/5 : 5/2 = 18/5*2/5 = 36/25.

    a b/c = (a*c +b)/ c.

  6. 3 3/5 = 18/5

    2 1/2 = 5/2

    18/5 / 5/2 = 18/5 * 2/5

    = 36 / 25

  7. Numerator:

    3 + 3/5

    15/3 + 3/5

    18/5

    Denominator:

    2+1/2

    4/2 + 1/2

    5/2

    Therefore,  18/5 / 5/2

    Reciprocate the denominator and multiply it by the numerator

    (18/5)(2/5)

    36/25

  8. ( 18 / 5 ) / ( 5 / 2 )

    ( 18 / 5 ) x ( 2 / 5 )

    36 / 25

  9. 3 3/5 : 2 1/2 =

    18/5 : 5/2=

    18/5 * 2/5 = 36/25

  10. make them improper

    18/5 divided by 5/2

    then multiply 18/5 by 2/5 (reciprocal of 5/2)

    and there you have it 36/25

  11. (3 3/5) / (2 1/2) (change mixed numbers into improper fractions)

    (18/5) / (5/2) (change division to multiplication and switch one of the fractions to its reciprocal)

    18/5 * 2/5 (multiply numerators and multiply denominators)

    36/25 or 1 11/25 <===ANSWER
