16 similar writing pads and 24 similar jotter books are stacked in a pile. their total thickness is 14.4cm.Each writing pad is 3x as thick as each jotter book. what is the thickness of the pile of jotter books?
Please show me a non-algebraic method of solving this.Thanks

  • maths -

    16*3x+24x=.144m

    solve for x, the thinkness in meters.

    Non algebratic....
    total thickness=sum of thicknesses
    =24T added to 16+16+16 T

    = 72 T

    or T=.144/72 or .02m or 2mm thick.

    If you haven't had algebra, we can't
    use 3x. We should say 3 times as hick as each Jotter book.

    Jotter = 1/4 of the whole.

    Pad = 3/4 of the whole,

    1/4 + 3/4 = 4/4 = 1 Whole.

    Jotter = 1/4 * 14.4 = 3.6cm.

    Pads = 3/4 * 14.4 = 10.8cm.

    Check: 3.6 + 10.8 = 14.4cm.

    Is this what you want?
