The Benefits of Buying CPO Nearly all manufacturers now have certified pre-owned cars for sale.
The sum of a rational number and an irrational number is irrational.. By definition, an irrational number in decimal form goes on forever without repeating (a non-repeating, non-terminating decimal). By definition, a rational number in decimal form either terminates or repeats. If you add a non-repeating, non-terminating decimal to a terminating decimal, you still have a non-repeating, non-terminating decimal.
Put the repeating digit over a denominator of 9. So we see that in the case of 0.3333333...., the repeating digit is 3, and we make the fraction 3/9, which reduces to 1/3. If there is a group of more than one digit that repeats, 1  Put the repeating group of digits over as many 9 s as there are digits.n the number 2.345, the last decimal place value is the thousandths place, so we put the digits 2345 over the denominator 1000. Of course we would usually want to reduce the resulting fraction to its simplest form.
