terminating decimals -- just use the rules for place settings in the decimal system to write a denominator.
ex. 3.2 --- the 2 is in the tenths place so --- 3 and 2/10 then reduce
ex 5.31 --- the 1 is in the hundredths place so --- 5 and 31/100 etc
Repeating decimals msy be done with a little algebra
ex 3.111111...
let x = 3.111111.... --- since only one digit repeats multiply by 10
so 10x = 31.11111... ---- now subtract the original equation
-x = -3.11111... -- and all the repeating numbers cancel
9 x = 28 ---- divide by 9
x = 28/9 ---- don't really divide reduce the fraction
x = 3 and 1/9
