    just divide the number after the decimal point by 1 followed by as many zeros as there are decimal places

    example: write 0.25 as a fraction.

    solution: there are two decimal places, so we divide 25 by 1 followed by 2 zeros, that is, 100.

    so we have 0.25 = 25/100 = 1/4

    Hello, shamonica!


    Converting fractions to decimals . . . use long division.

    ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~


    Example: \frac{13}{20}


    Divide 13 by 20.
    Code:
                  0.6 5
              --------- 
          2 0 ) 1 3.0 0
                1 2 0
                ----- 
                  1 0 0
                  1 0 0
                  =====

    Therefore: . \frac{13}{20} \;=\;0.65


    ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~


    However, most fraction do not "come out even."

    Example: \frac{4}{11}
    Code:
                0.3 6 3 6 ...
              ---------------
          1 1 ) 4.0 0 0 0
                3 3
                ---
                  7 0
                  6 6
                  ---
                    4 0
                    3 3
                    ---
                      7 0

    Therefore: . \frac{4}{11} \;=\;0.3636\hdots

    This can be written: . 0.\overline{36}\:\text{ or }\:0.36\tfrac{4}{11}

    haha, i read convert "decimal to fraction" as opposed to "fraction to decimal"

    people usually ask how to go from decimal to fractions, so i was replying out of habit. thanks for looking out
