question to check - decimals dot notation
Hi my friends,
I need a second oppinion. My books asks me.............Write the recurring decimal 0.57373737373... using dot notation.
I gave the answer. 0.573 with the dots over the 7 and 3
The book gave. 0.573 with the dots over the 5 and 3
but the "5" does not recurr? It must be my age again....LOL
Thanks again

Re: question to check - decimals dot notation
Hi silverpuma;
That is what I would do also. You are correct the 5 does not repeat.
In mathematics, you don't understand things. You just get used to them.
If it ain't broke, fix it until it is.
Always satisfy the Prime Directive of getting the right answer above all else.

Ccea-Foundation-Mathematics-Rosie-McCrae I tried to send the amazon link but was blocked.
I am really enjoying the book a full 630 pages with loads of test questions. The answers (another 105 pages) are on the hodder website for free so you get lots to work with. I need all the help and practice I can get......

Re: question to check - decimals dot notation
:(hi silverpuma
I think you want
which is what you said at the beginning. Your book seems to have a lot of typos. Tut!
That is a dot over the first and last numbers that recur.
so 0.142857142857142857....
would be
