  1. female ---- x
    male ---- x + 5/8

    x + 5/8 = 29/8
    8x + 5 = 29

    you finish it, ok?

  2. Let female=x
    male= 5/8+x
    3 5/8 pounds is the same as 29/8 (this is the improper form, it's easier to write it this way).

    x+5/8= 29/8
    Subtract 5/8 on both sides (we do this to get the x by itself).

    x= (29/8-5/8)= 24/8 which can be simplified down to 3

    x=3

    The male kitten weighs 3 pounds.
    Hope this helps.

  3. Male + Female = 3 5/8
    M + F = 29/8 (Normalized 3 5/8 to 29/8)

    Male = Female + 5/8
    M = F+5/8
    Male which is 5/8 times Female plus Female is equal to 29/8
    (F+5/8)+F=29/8
    2F=29/8-5/8
    2F=24/8
    2F=3
    F=3/2
    F=1 1/2

    So female weight is 1 1/2
    Male weight = Female + 5/8
    M=3/2 + 5/8
    M = (24+10)/16
    M=34/16
    M=17/8 = 2 1/8

    So Male weight = 2 1/8 lbs
    Female weight = 1 1/2 lbs
