    Multiplying out Fractions - Help with basic question

    Hi all,

    So I am going through a workbook and it has this question:

    6 ( 1 + h/2 )

    This is how I did it:

    6 x 1 = 6

    6 x h = 6h
    6 x 2 = 12

    = 6 + 6h/12
    = 6 + h/2

    But apparently the answer is:
    6 + 3h

    Can someone tell me where I wen't wrong?
    The text book doesn't explain it and I am so confused.

    Thanks

    Oh I think I figured it out.

    6 ( 1 + h/2 )
    6 x 1 = 6

    Then to multiply fraction we do:
    6/1 * h/2
    = 6 * h = 6h
    1 * 2 = 2
    6h / 2 = 3h

    = 6 + 3h

    I needed to turn 6 into the fraction 6/1

    Is that correct?

    Yes, in your first attempt, you multiplied the second term within the parentheses not by 6, but by 6/6 = 1.
