i have a problem with changing fractions to decimals. For instance if i have the fraction....121/239 and i have to write it as a repeating decimal i am not sure how to go about it. in my example it says...(121*4649*9)/(239*4649*9)
Which equals 5062761/9999999 and can then be written as a decimal. However i am not sure where the 4649 and the 9 come from. if anybody could help me on this topic it would be good thanks.
