    What I got for the last vector one
    a) 2q-p or -p+2q (don't remember this one lol but I think it was something like this)
    b) 1/2(2q - p)
    = q - 1/2p
    (last bit)
    OP = p
    QR = 1/2p
    therefore OP = 2QR
    so they are parallel

    I put the same but I just guessed lol

    I'm pretty sure it was yes, I think I did something like this:

    4/20 x 3/19 = 3/95
