    Answer:

                  5 and 6

    Step-by-step explanation:

    a – first number (the smaller one)

    b – second (the larger one)

    The difference of two number is 1, so:  

    b – a = 1    ⇒  b = a + 1

    Their sum is 11, so:

    a + b = 11

    a + (a + 1) = 11

    a + a + 1 -1 = 11 -1

    2a  = 10    ⇒   a = 5

    b = a + 1 = 5 + 1 = 6
