A board that is 12 feet long must be cut into 2 pieces that have lengths in a ratio of 3 to 2. Find the lengths of the two pieces.

  • geometry -

    Let x = the longer piece.

    3/5 = x/12

    5x = 36
    x = 7.2

    12 - 7.2 = ?

  • geometry -

    variable L= length
    and we have 12:2 is = 6
    and then the ratio 2/3
    is 2/3 L=9
    check:
    12-9=3 If they asking continues answer will be 3
    so both sides are make sense
    6=2/3(9) check from the 12 feet long we have 12= L+3= 12=12
    if this helpful
    6= 6
