Thread: fraction and decimals need urgent help

how do you change a 39/43 in to a decimal and also how do you do long division? sorry for keeping on changing it! again

If you divide 39 by 43 in a calculator, you will receive the decimal representation.

To 7 decimal places, 0.9069767

thanks for the help but how do you do it without a calculator?

it depends upon how many digits you want, kind of.

So for your problem you could do this:

Its obvious that (39/43) = (1/10)*(390/43) = (1/100)*(3900/43) = ...

So you can multiply 39 by, say, 10,000 and then do regular long division, and then divide your answer by 10,000 at the end.
