    Q is a point on segment PR. If PQ = 2.7 and PR = 6.1, what is QR?

    From segment addition, we know that:
    PQ + QR = PR

    Plugging our given numbers in, we get:
    2.7 + QR = 6.1

    Subtract 2.7 from each side, and we get:
    2.7 - 2.7 + QR = 6.1 - 2.7

    Cancelling the 2.7 on the left side, we get:
    QR = 3.4
