    the statements says that the number of cats is equal to: "seven eights" of my cats plus two that means that the "two" must refer to the remaining cats, which represent one-eight of the total. do you understand so far?

    we are told that the number of cats is: "7/8" of my cats plus 2 this can also be stated as: "7/8" of my cats plus "1/8" of my cats (since 7/8 + 1/8 = 1) make sense?

    so now you can see why the "plus two" means that the "two" represents 1/8 of the total number of cats?

    no - remember the 2 represents 1/8 of the total number of cats. so if 1/8 of the total is 2 then how many cats altogether?

    lets call the total number of cats c, then we can write:\[\frac{c}{8}=2\]so what will c equal?

    1/8 of 8 is 1. so that cannot be correct.

    1/8 of 1 is 1/8 - you cannot have an eight of a cat - at least not one that is alive! :)

    I would love another! and or also can you help me on this one... the gasoline gauge on a van initially read 1/3 full when 10 gallons were added to the tank the gauge read 3/4 full how many more gallons are needed to fill the tank?

    no - remember - the first step is to work out how much of the total number of cats is represented by the 9

    you are told that the total is "two thirds" of my cats plus 9 so the 9 must represent what fraction of the total?

    remember "two thirds" have been accounted for - so what fraction remains?
