Hi,
Repeating Decimals are very interesting. We can express them as fractions, and also decimals with a line above the repeated numbers. Prior to this we could not define them mathematically as a fraction. With the formula a1/1-r we can. This is a very easy formula to use, and for things like 0.33333.... we just take (3/10)/1-(1/10) So then we can get 1/3. Overall, this is a very easy and helpful lesson. Hopefully it will show up more on the final because that would be enjoyable.
Thanks,
Kaili Chiu
