Question

One third as a decimal

Answer 1

.333333333 ect. so the three is a repeating decimal. hope this helps. :))

Answer 2

One third is one of those rational numbers that can never be
exactly written as a decimal. To change a fraction into its
decimal, you divide the top number by the bottom number,
and the quotient is the decimal form of the fraction.
When you divide 1 by 3 , you get .333... and the 3s never
stop. They just keep going on forever.
That's called a "repeating" decimal.
